This game refused to start on my pc. It stated that I had a CD\DVD emulation software on my pc and it had to be removed. Ubisoft copy protection is to blame. It looks for any clone software such as CloneCD, Alcohol 120%, Daemon Tools, etc., that use CD\DVD emulation. If it finds any it will not start the program even though you have the original Ubisoft cd in the drive. What they are doing is telling you what you can and cannot have on your own computer. After I found this out, I brought my Chessmaster 10 back to Best Buy. The computer tech geek there was so upset when I explained and showed him why there was a problem that he gave me a full refund despite a store policy of no refunds on open software. He said he had some of this same clone software on his own pc. As for me, Ubisoft has lost a customer. Never again will I buy their software.
