我的是正版的..现在不知道怎么办了.
求大神...

难道正版KEY激活次数有限制？

ArmA 2 OA CD Key ChangerIf your CD Key ever gets banned, and you feel the need to change your key either edit your registry by starting regedit in administrator mode and navigating the to the following keys:
HKEY_LOCAL_MACHINE\\SOFTWARE\\Wow6432Node\\Bohemia Interactive Studio\\ArmA 2 OA\\KEY
HKEY_LOCAL_MACHINE\\SOFTWARE\\Bohemia Interactive Studio\\ArmA 2 OA\\KEY
The problem it is stored in REG_BINARY, so we have a small program for it. This program also displays your ArmA OA CD Key in case you have lost it and need to save it for later use.
