I've been having the exact same problem, everytime I log in, my game just crashes. It doesn't give me a Disconnection Error before it closes nor does Xing Anti Cheat tell me I had 3rd party programs running in the background. I get no messages at all, the game just simply shuts down 1 minute after being in lobby, or just 1 minute of having AVA.exe running. I also tried joining a game right away, but it still closes.
I've tried mostly everything to try to solve the problems.
-No programs running in the back ground
-No macros
-Deleted Xing Folder
-Deleted Logs
-Re-installed AVA
I need a solution.
