A reoccurring problem I have when (re)installing Call of Duty: my second disk won't load mid-setup.

I pop in my Disk 1, and it brings up the window, I hit install and It gets to about 46% percent and asks me to insert my Call of Duty Disk 2. I do, but it doesn't do anything. In fact, my setup freezes until I pop the disk out of the drive, and it asks me to insert it again.

Any ideas?

Yes, this has happened before, but it eventually worked after a few days somehow.

I still have the multi-player files such as custom maps, mods, etc.

Does your disk have any smudges on it or anything that might cause read errors?

No, it doesn't appear to have any smudges or scratches on the surface.

just to be sure, you should clean the disc in the cdcleaner. Otherwise you should look over your cd reader. That's the hints I can give ya
