Ok, I recently just bought Arma II and Arma 2: operation arrowhead, one day playing with my mates a hacker came on my mates immediately backed out but I was afk. now everytime I try and join a server it says "CD Key in Use" I searched this up on YouTube and Google like 50 times and I tried a bunch of fixes one of them said to change my key in "Regedit" in "run" and it said to change the key to what I have now. I didn't know about how you only get 1 key and all but I didn't try and hack at all I didn't do anything. I am now global banned and now I hear that the only way I can get unbanned is by buying another arma 2:OA. PLEASE HELP!!!! I cant afford to buy the game again I know its cheap and all but I used my pops account and he wont buy it for me again I was lucky he even bought it at all and it was on sale... Please help or help me get unbanned I seriously didn't do anything at all if you really want to u can ask the admin to check the logs of the server I play on and I guarantee u wont find anything about me spawning shit in. the ip is 64.94.100.86:2332 if you really want to check!
