I tried every fix suggested by you guys (thank you for the quick responses), yet nothing worked. I also want to point out that I always launch steam first but even trying to launch ETS2MP without steam already running didn't work. I have attached a screenshot of the error message, maybe that will help in understanding the issue. And (just because I've read useless stuff in other forums) keep in mind that this only happens when launching the game via TruckersMP, singleplayer works fine.

So, my ETS 2 just updated to 1.30.2.2 and after the TruckersMP update I tried to launch it, but all I got was a prompt saying "The game filesystem failed to initialize." I tried everything: Verifying game cache, reinstalling TruckersMP, reinstalling the game, reinstalling the TruckersMP ProgramData folder, reinstalling both TruckersMP and the ProgramData, yet nothing helped. If I launch the game in singelplayer, however, everything works fine. Launching both steam and TruckersMP as admin leads to the same error. Launching steam as admin and running TruckersMP as a non-admin results in a singleplayer session for some reason. I don't think this is important, but I recently updated my Windows 10 from 1607 (anniversary) to 1709 (fall-creators). Does anyone know why this might be happening? And more importantly, what can I do about it?
