I've been playing Arma 2 OA for a while now and I've never had any issues at all until today. Yesterday I played it normally, but when I tried to join a friend in-game I couldn't find neither his server nor any others. I checked everything and the game was outdated. When I tried to update it, it said that I have wrong CD key. Even though it installed the update, the servers never popped up. I tried running the game without Steam or with Six updater and it didn't help. Arma 2 works perfectly and all mods related to Arma 2 OA (DayZ and Ace) and I can connect to their servers normally. I even checked if my PC has any viruses - nothing. The last thing I'm trying to do is reinstall the game. It's reinstalling while I'm posting this, but in case it doesn't fix the problem - what to do?
-Thanks in advance, Alnick
