SW: Republic Commando Issue

[gameover2145]

I am having some trouble with playing SW:RC. The game is installed, I mount the .iso image in daemon tools, and the a SW:RC menu appears. When I click start game, I get this error message: "Wrong Disc Inserted. Please insert the original disk into your CD/DVD Drive." I'm not exactly sure what to do, any help would be appreciated, thank you.

iso is not a good format for protected games.. you need to use mds/mdf.. how did you make the image?.. does the same problem happen when you use the original disk?
