Hey everybody! After buying myself a new pc and installing steam, ArmA 2 , ArmA 2 Operation Arrowhead I've had a little problem with trying to update the OA version. Everytime I'll try to patch the game it extracts and pops up and error "Wrong CD KEY". I know this might not be appropriate for a DayZ forum but hell i'll give it a try. I've tried to check files on steam and nothing was wrong, run the game few times, installed battle eye but nothing seems to work as for other people. I haven't downloaded any 1337 hacks just maps like Taviana, Namalsk, Utes and Takistan. Everything is bought legally no scam. PLEASE HELP :(
