After installing the new patch update in the autoupdater this message started to popup when starting LFS:

DI : DirectInput8Create - DIERR_GENERIC

Besides that, the game seems to work just fine with working single player, training and hotlapping modes, but as soon as I try to enter any server my game literally shuts down by itself, btw this didint happen before this new patch update.

Same story there, turned out it was the "antivirus" messing with DirectInput.
