What happened here is this. I tried to click ATSMP which worked perfectly fine for me until today. When I tried to get on the game, the game had a black screen and I couldn't do anything for the first few times. I restarted my computer & reinstalled the program. It happened again even though I reinstalled it for some odd reason but it seems to be happening before Steam opens up. Should I try to play the regular ATS and then go too the multiplayer version to see if that could fix my problem? If interested, I got the file directory installed here.
C:\Program Files\TruckersMP
Isn't it suppose to be there? After all, it's the default directory so I let it downloaded there. I will try to play the base-game now and then go try MP. If that fails, I will report back and post my results.
