Same issue. Content Manager is fine. I've submitted a ticket about it. I'm using the Steam version and I've heard this has been a problem before. Auran can we can any clue as to what's happening? Really wanted to spend my weekend playing with friends but that's now impossible.
I believe it went down Saturday about 3;15am cental time. Was on when I thought I had a sync error. Went to reboot but no itrainz chat light & no sessions.Alway's seems to happen on weakends when you actually have time to play.lol Talk to ya later buddy.
