Hello, I've come to this thread as a last resort, as I've tried everything else before coming here.
My problem occurred the day after I downloaded the launcher, I played two times before experiencing any problems with the game or launcher. After a good time of exploring and looting on Overpoch US 1, my friends and I decided to log off for the night. I woke up the next morning, excited to hop back on and see what we could do for the day. Trying to log in to the server, I was greeted (before I even got to the lobby) with an "Session Lost" message. I've tried everything I could think off, here is what I've done.
Uninstalled and reinstalled Arma 2 and Arma 2: OA
Verified the game caches of both of those games on Steam
Verified the mods: DayZ Epoch 18.104.22.168 and DayZ Overwatch 0.2.5
Uninstalled and reinstalled the CCG Launcher
Updated my video card drivers, and installed Windows Updates
Restarted my computer
Launched Arma in a different version and re-launched it in the most recent version
The only thing that worked was installing the windows update and restarting my computer, and that only worked for a short time, before it quit working. If anyone has had this problem and has resolved it, It would be greatly appreciated if you shared the solution! Thanks! -Lazer
