Microstudio 3.004 Reinstallation Problem

[Bossard]

I had to reinstall Windows on my computer and everything else afterward. I have Microstudio 3.004 on a disk as a backup from MTU when I purchased it. When I try to install it I get a message stating: The machine you are installing on does not match the machine registered on this removable storage. I contacted MTU and they replied the next day it is okay to install now but I still have the same problem. I contacted them again and they asked if I kept Windows updated which I do. They said it would not install otherwise. Since I am installing from my original disk I don't see what difference that would make anyway. They no longer have this version as an internet download so I must install from the disk. Does anyone know why this won't recognize my computer.
