Try closing steam and execute steam again (and running mp as administrator). Game/Mod is in alpha-stage, so there are a lot of known issues. So don't expect that much.

Got the same problem on Ultra settings with some trailer-backlights, too.

I think it is a known issue. But in general ETS2MP has the double of the requirements of the singleplayer version. And according to steam 4GB RAM are recommended for singleplayer. So more than 8GB should be enough. Just send the log-file. It'll help the programmers to solve this problem.

Sometimes, I got the same error with keyboard, maybe it would help, if you would try it more that just 2 times. Try it more often. If it still doesn't help, come here again
