Cd-ROM only reads copied discs.
 

My Cd-ROM will only read backup copies of my games. It won't read the original disc's. I noticed this problem when I bought Combat Flight Simulator 2 and I had to unload and reload the disc about 10 times to get it to read. After it installed it would no longer read the disc and I have to run the game out of my burner. And now my cd-rom won't read any original discs, it only reads backups.
