Can't get new games to run Since I downloaded SAFEDISK (Playback21)

[Covey]

I was wondering if someone could help me out with the Crazy Cowz playbackup 21. I just purchased 2 brand new games (Original Myst3 and Max Payne) and I cannot get them to ####tup. I know it has something to do with playbackup 21(image patcher) because I just had to do a total system recovery on my computer and afterwards I tried to play these 2 new games, and they both ####ted up fine. But then I tried to play some of the games I made backup files for and they would not run. So I then reinstalled Playback 21 and now they work. But now the 2 new games don't run. I think it has something to do between Demoshield32 (because I used to get a error message about Demo32) and Playback21. I have tried disabling it and then ####ting the games but that doesn't do anything at all.
Is there a way to fix this or is there a better image patch program to use?
