Unable to copy files from CD

I’m unsure whether this is the right forum, but anyway…

The problem is, when I try to install Rome: Total War (retail, not copy), during the installation I get error messages saying like “unable to copy this file”…
And I can’t copy from the disc manually either. (And I’ve tried different drives too).

It worked fine when I bought it some time ago, but probably the disc has received some kind scrath or the files have been corrupted or something.

The thing is, all would be fine if I just could get the installation program to not try to copy the file. The file in question is just a intro movie, and the game would run fine without it. So what I’m asking for is essentially a way to bypass the copying of that particular file. Any suggestions?
