I reinstalled Call of Duty 4 a couple days back with the install disk and everything went smoothly. The multi player function works perfectly (as it does not require a disk check) but when I insert the disk for Single Player I get unable to locate DVD-ROM error. Call of Duty 4 is in the disk drive and from what I can tell no new drivers are needed for my drive. It looks like the software can't "see" the disk.
What do I need to do?
Thanks
