Ive been getting the session lost on the game for a couple of weeks - during the 0.5 and the 0.51 patches - and am still unable to join any server. I have tried:
- verifying the game cache
- deleting battleye and letting it update
- reinstalling the game
- disabling my anti-virus
Ive spent more time reading and trying to fix it than actually playing the game. I dont know what else to do.
