Right, so i just opgraded from Windows XP to Windows 7, and i've
installed Mass Effect, but the problem is that it wants me to purchase a
new registration jey in order to play, as the one i used in XP is
already used (obviously? ) is there anything i can do to solve this or
do i really have to buy a new game/reg key?
COntact EA suport. The DRM included with ME only allows for it to be installed a limited number of times before it locks itself out.
The correct procedure, which they dont tell you, is that you have to un-register and uninstall the game, before you reinstall it.
