I have made a backup of my mohaa cd in the past. I copied according to the protection used which I think was safedisc. The backup was successfull, I installed and ran the game for a few weeks.
Since then I have reformatted my hard drive and reinstalled windows xp. Today I tried to install mohaa using my backup copies and they won't install. I tried several times but kept on getting a crc error.
I don't understand why they wouldn't work now when they worked before. I have also had the same problem with motogp, only this one let me install but asks for the correct cd when I try to play.
Both of these games were working copies .
Any help or suggestions would be greatly appreciated.
