Risk II Shuts Down - CDROM Error #7, Disk Has Bad Block

> Hi All, Most the time I can play my game ok in XP Pro.
> Sometimes it quits. I can look up this error after the
> game disappears without warning. It's the same error each
> time. The game plays without error in W98se consistently.
> I can't use w98 settings in XP Pro and get it to play. It
> won't. I have even replaced the cdrom drive but to no
> avail. I have tried playing the game from a copy on the
> hard drive but copy protection won't let me. OK. Should I
> try to find a new disk or is everyone else having this
> problem? I'll build a w98se machine just for this game if
> I have to.
