Hello,
I hadn't played for about 5 days and went to launch the game today only to find that the Login / server select screen never appeared and it took me straight to my profile. I clicked continue game and it shows signing in but when I'm in game the Tab key does not bring up the player list and I can see no other users around.
Edit: Yes I am launching from the TruckersMP shortcut, and I did try running as Admin but did not solve the issue. Didn't have a lot of time last night to fool with it but I'll try a reinstall of both the game and MP client today after work and report back here.
Edit 2: reinstalled MP client and made sure to set it to run as administrator which solved my issue. I am now back to playing online, thanks y'all!
