Did you try the desktop install GloryofSparta suggested? Copying the files from the CD first might work, because every CD has a great deal of rudundancy (error correction) in program files. As long as your scratches are radial, not circular, you have a chance.
Try cleaning the CD with mild detergent & a clean soft rag. Move from the hubcenter, OUTWARDS with your cleaning strokes. This is because of how data is stored.
This is a perfect lesson in why the US Federal Law exists (Title 17, Section 1): you bought and own the game, yet cannot perform required maintenance because you did not make your own legal archival backup, beforehand. Note: the Title 17 personal archive of legally owned software is a single duplication of each disk, stored and not shared with any other person or machine except to maintain your software on the legally installed machine). Though the files you listed are 'harmless' by themselves, they are copyrighted. The same Title 17 that protects your rights as a purchaser also protect the copyright owner, Activision. And unless Activision authorizes HG to post even some of its files (they have not, to my knowledge), we must respect that.
Now for GOOD NEWS. Activision will replace defective disks, at the retailer where you bought yours. Take them in, and ask for exchange. They may require your reciept, but will do it (Activision requires it in their store contract to sell their games). If they complain about the dated reciept (e.g., more than 90 days), then give your disks as a gift to a buddy who got them for Christmas, and let your buddy exchange them. Maybe your buddy might give them back, and then you will of course make your own Title 17 archival backup. For example, here and here are examples of where Activision officially tells people with bad disks & bad serial numbers to return them to the retailer for exchange (no time limit, if your retailer is 'snotty' about it)...
Quoted from Activision defective disk return policy:
If you stll have problems then you may have a bad disc. Return the game to the store you bought it at for an exchange.
