I don't know if I should be posting here... but it was the only one I saw fit because the "help" threads are BeamNG related only... (I think so) Anyway, the title says it all... What should I do? (It can't play any of my games, not just BeamNG...)
Steam is down. Either Steam got ddos, or the winter sales where way to extreme and people crashed steam.
Navigate to your Computer>(C>Program Files (x86) or whatever you have>Steam>steamapps>common>BeamNg.drive and you may launch BeamNG.drive.exe from there, no steam or steam sign-in is required. Steam hours don't count either but it works. HF
Multiple hackers have claimed a DDoS, and some of the Steam Support areas are citing that as the reason for the downtime (the rest are remaining quiet, probably trying to fix it.) Here is one of the hackers.
It could be the sales causing steam to go offline, and they are taking advantage of it for RT's... Check the replies.
