OK, just found the solution in my case...

well, kind of...

I killed off every single program running the background and now its working again.

There is clearly some kind of conflict going on there. I will update this when I know the exact problem, but going to bed for now.

Night

I know I resurrected a dead thread that no-one had offered help with, but... seriously, can anyone shed some light on this topic?

I did a bunch of googling last night on this topic, I ended up deleting registry settings, deleting and re-installing Logitech profiler, the drivers and LFS. I tried doing all of the above in a different sequence. No luck. Then randomly it did work with full FFB. Amazing. Turned off the computer last night, but today no luck

My old computer died and I basically built a new computer purely to keep playing this game and now this... The game is completely unplayable in its current state. Desperately looking for ideas.

Same problem here...

Worked fine, bought new computer so everything is a fresh install. FFB works in other games, absolutely no FFB in LFS

Wouldn't be a huge problem execpt that other games suck
