ok. ok. I did just get a games for windows live update on my windows update so maybe that'll help.
It's not going to help your disc at all, it's either dirty or damaged. Getting a Cyclic Redundancy error means that your computer can't read the disc properly, either because the it's dirty or damaged or because your drive is faulty. No outside software is going to be able to help with that. Try giving it a cleaning, that might work. Otherwise you're SOL.
