when I download the set up it says C: Program Files (86)/ Z8games/ Crossfire.exe An error has occured while trying to replace the existing file: DeleteFile failed; code 5. Access is denied. Click Retry to try again, Ignore to skip this file (not recommended), or abort to cancel installation. I've installed the game multiple times haven't been able to play for a week not that that is important but i've tried all the mirrors and still its doing the same thing I waited for the patch thinking that would solve the problem and that failed.What do I do? Can someone help me would be very helpful thank you.
