I'm just wanting to see if the community has run across this issue (as it was suppose to be fixed with a previous patch of ArmA2) and if they have any ideas on correcting it. I am running a DayZ server and have gotten reports that a few players can not login and are getting an error message that says that the 'CD Key is in use'. I dismissed it as just, "Oh they're just using a keygen or something and someone already has it." Well I kept getting these reports so I looked into it and had a few people send me the registry file that contains the key for ArmA2OA. Sure enough, every player had a different key, and when I checked the MySQL character_data table I had a very high number of identical PlayerUIDs. It's either someone never stopped playing this game and sucked at it, or I/we have an issue. I've found PlayerUID spoofers that would be an easy work around but may also expose the game to other types of hacks in-game. Each player (three of them so far that I know of) all have separate, completely different, keys but when they log in their PlayerUID is the same. Any one else run into a similar issue?
