Hi, just wondering, I've bought a retail version of S2 University, and it installed fine, but when I try to run it, it says : Please Insert Correct CD/DVD : and yes I have put the CD 1 in and yes Iv'e tried CD 2, anyone got any advice??? I tried using a NO CD Patch/Fixed EXE and Iv'e even resorted to Fixed Image Patch, but nothing. The original EXE is back now, any advice please?
