Hmm... I'm not sure if anything has been changed, but as soon as you meet the minimum requirement for any given car - you should be able to drive it.
Try the command;
!infos
Say you do that in cargame.nl S1 server, for FXO (which is a Class 2 car) you will need at least 150 points (!rank) or 200 experience points (LFS EI - which is calculated from your online + hotlap stats) AND a minimum of 60% safety rating (!rate).
Try
!info
to find out how to earn points.
LFS EI: From the Airio website (http://stats.airio.eu/EXP.aspx)
The safety rating is crucial: its based on number of cautions (yellow flags) that you are involved in + some other stuff (getting kicked/swearing etc.). Simply try and stay out of trouble - Remember that you will cause a yellow flag if you slow down on track, even if you don't cause and incident.
To see your stats in-server, type !pi.
Every few races check how much points your earning and if you're managing to increase your rating. Good luck!
--- Edit ---
Hmm. I can see why the restrictions do look a bit harsh for new LFS users. However you won't have a problem with the safety rating - dozen or so laps and you'll have the minimum safety rating.
You might have a hard time reaching the required points or the required LFS EI. For those of us who started on the servers a while back there were plenty of drivers with XFG/XRG - so it was easy to gain points if you consistently finish races in relatively good positions. Nowadays however, there are not many drivers with those cars - even when there are they might be lapping significantly faster times than you (therefore you won't be gaining much points even if you finish the race). For those of us who've been driving at various combos over the years (even if it meant not too competitive racing) would have acquire a LFSEI higher than 200.
What I can suggest is that get a good feel for your controller, the car and its handling. You can request setups from other drivers in-server (although some people don't like to share their sets) or you can download setups from http://setupgrid.net/ or http://setupfield.teaminferno.hu/ for the car/track combo of your choice.
Being able to drive fast(er) isn't enough - you'll have to be able to drive amongst other drivers as well (I'm still trying to get the grasp of that!). There are plenty of servers that run XFG/XRG on BL1. Stick to it for a bit and improve your race-craft. Once you can consistently do good laps and race well with others, you won't have too much of a problem switching to other cars. The "Demo" BL1 servers can be a bit of a headache - so make sure you visit a well-administrated one. The [AA] and Redline Racing servers are pretty good. The Redline Racing guys are a pretty helpful lot.
It was the reply to the post above (pretty much my reaction too) when I had to manually control my jaw, blink, breath, trying to scratch an itch whilst final countdown was playing in the background... Thankfully Morgan didn't start speaking.
Since you've been practising with the FXO it shows that you have already unlocked S1. However, you can check it in the LFS entry screen: it'll read S1 licence: BobBCN
One S1 host where you can race the FXO is "Cargame.nl S1".
Try joining that host and see if everything is ok.
With a S1 licence you should be able to connect and drive in S1 and demo hosts. In the hosts page, you'll see S2 hosts, but you wont be able to connect; I think the message reads "host is S2".
Yes, the fix is for Vista, but someone posted saying it works for another Saitek device on Windows 7 (64 bit) but another saying the fix wont work on Windows 7 (32 bit)...
Although the Saitek thread has not been updated in a year, you can try and make a post there if the above fix wont work.
Oh, oh, make it a "Post your RC / Die-cast vehicles" thread! I've got loads of the latter and I'm sure there are other enthusiasts on this forum (no point in making a separate thread).
Set to 15 minute qualifying and 10 lap races (the actual number of laps for the race will be notified by tibone). Feel free to use the server and get you friends to race there as well.
As Gav mentioned talking about changing the shape of the original cars cannot be discussed here.
You can add custom sounds or make your own. Yes, you can add BOV sounds (but the car should have a turbo - non of the current demo cars are turbo charged).
Have a look through the sub forums that has already been posted; I'm sure you could find couple of stuff to add.
I'm not sure why you've posted this inside a PRISM sub forum (unless your question was related to PRISM or similar software...), but non of it is needed for you to enjoy "original" LFS.
What changes were made between the last time it worked and the first time it happened? Did you install any windows updates recently? If that's the case you might be able to go back to the previous restore point and try... Although I don't think I've heard of a Windows update getting in the way of the profiler...
When you tried re-installing the software, did you remove the existing installation first?
When you say you tried downloading the profiler - did you download the correct version that is suited for your operating system? If possible, can you add the link to the driver that you downloaded? (For example, this is the driver/profiler download for the a DFGT on Windows 7 - you've got to select 32/64 bit)
If I recall correctly, even if you don't have the profiler installed - LFS does correctly recognized the device (for example in Options > Controls it should say Logitech DFGT). Does LFS recognize the device correctly?
When you install the profiler - have you followed the steps correctly? For example, you should only plug in the device's USB when requested - the calibration might not work properly if you have already plugged in the USB before you started installing the profiler...
