Uploaded a new version, but it's not finished yet (as you can obviously see). I had uploaded this intermediate version to at least fix the direct replay loading issue (if you select two replays on lfsworld and click 'compare')
I get that host status value directly from LFS. It represents the current state of the host and who can join it.
The internal setting for the "mode" value only determines which tracks / cars you and clients (if allowed) are able to select.
Electron used to only work for UK customers. At our payment gateway at least. I'm not sure that's changed - starting to look like it has not.
In that case I'm afraid you cannot use the credit card option and will have to use paypal or another method. You may be able to use the direct payment option if you do not have an acount there.
