Well, if the disc is damaged, then you should return it to the store from which you purchased it and either get a refund or a replacement. Frankly, I think you should ditch UT2003 and get UT2004, preferrably the Editor's Choice Edition on DVD. UT2K4, in case you didn't know, includes all the content from the previous game, and more. It includes optimized netcode, enhanced features (built-in music player, demo recording and playback from a menu, Community chat and loads more), more gametypes (including the return of Assault and the addition of Onslaught), plus tons and tons more stuff. If you pick up any of the DVD editions of the game, you will also get a second disc featuring dozens of Video Training Modules that show you how to make all kinds of stuff for the game. The main game disc also includes 3D modeling and painting software to get you started right out of the box. Go to the
Unreal Tournament Web site for more details. If you can't return the disc, then I suggest you try cleaning the disc off with one of those off-the-shelf disc cleaning kits (Discwasher, et al).
