Hello DSM,

i checked the log and i ends right before loading the move in the mainscreen.
There was also an error inside the ShowEscapeDialog (Did you press [ESC] while loading the game ?)

please make sure you played the game at least once over steam.
(Start the game over steam and play a single game for 1-2 minutes and end the game.)

delete everything inside this directoy:
C:\ProgramData\FAForever\gamedata\*.*

start a game with the FAF client and see if you can reach the ingame lobby.

make sue you don't use any cyrillic chars in username or filepath etc.
Supreme Commander can't handle non english charactes very well.

Then post a new game.log.
