While disc one (the main game) works and installed just fine, the second doesn't work at all and any time I try to install it it freezes at about 50% and tells me to clean the disc.
No matter how many times I try to clean or install the Undead Nightmare disc, it will not work. It also doesn't work even when I just try to play it off the disc. This is the only disc I've ever had a problem installing. And as I looked around today for feedback (wish I'd done this beforehand), I'm not the only one with this problem and there is no solution for it except exchanging it and hoping you don't end up with another lemon.
IE: Some copies of Undead Nightmare (the second disc in this collection) are defective and will not work no matter what you do. I must just be unlucky to have received one of the botched copies. And I can't return it to Amazon either which really stinks.
