Help with an error message

[Nuuru]

I've gotten this error message for a few games that I've tried to run on my computer, from what I can tell it's talking about the original game disc but I've already used the .iso file so Im not sure whats missing. After using the iso file the game appears in my drive list but I still get this error. Anyone know a solution to this problem. Thank you.

what's the name of the game?...

it looks like siglus engine, maybe you could use cracker or alpharom to bypass it
