well i bought cod5 and i tried installing it. the first one i got i keep getting an error so i traded it in for a new one. the new one i got does the same thing but different files. but i think the problem is my dvd driver. everytime i put in the disk my pc goes all slow and it takes a while for my pc to read the disk and when it does it takes a long time to load a file if i click it. does anyone know how i can fix this or do i have to buy a new driver?
