Okay i have tryed almost everything now.. But everytime i try to open cd-key changer the it wont work..
And i cant download it from blizzard because it says my cd-key is already in use when i try to add the game.
I Lost the Roc cd.. Does anyone in here know if there is any way to get cd-key changer working on Vista?

i use "AWC" (Advanced Warcraft Control)
you can save any cd key in this program and switch between them
also u can change any wc3 settings with this program
