Using CloneCD, I copied the Sold-Out Software version of Worms 2 to my hard drive, and installed it. However, when I try to play it, it comes up with an error asking for the CD (I swear, it's a legit version).

make sure the drive letter of the virtual drive is the lowest out of all your CD/DVD/Virtual drives.

IE: A is lower then B, E is lower then F etc.

Thanks. It works now. I just had to disable the "real" drive (it wasn't working properly anyway, which was why I made the images) and everything is working great.
