Ok heres my problem, I bought and own a copy of GTA 4 from walmart, it worked fine on my XP 64 bit then I got windows 7 64 bit now my pc wont read the dvd roms at all? I can't even view them in my computer? Any help?
If the game disc worked fine in one OS and now will not read it in any way, I don't see how that would be because of Windows 7. Can you try the disc in another machine? When you put the disc in your machine and look in My Computer, does it not show anything in the drive? Can you browse the files?
