Thanx a lot for your help, i'm going to try that out now. From what u said it sounds like i didn't make myself all that clear. Yes its one of those programs that refuses to run unless the disk is in the drive, & although all the copies i've made appear to be exact copies, the cd drive just has a quick look at the copies then goes "okay, so where's the real disk then ?" (well not quite in those words). I've doen a few searches in other forums & some people have said that the program might uses securerom protection but they weren't sure. Dunno if any of this info helps at all, hope so !!
P.S. Yes to ur other question the program still recognises the original disk & will happily run away when that's in the drive
