So i have been dying to get this game basically for the DayZ mod. I basically got a new computer just so i could play this game, a custom built computer. So i go off to a retail store (JB-HI-FI) to buy this game, I bought it and i put it in my disk tray and it can't read the disk for some reason it just loads for like 10 minutes then says please enter a disk to continue and ejects the disk tray. I did all the Windows updates and went into device manager to update my CD driver it was up to date, i'm all out of ideas and i want to play this game so badly. Please someone help me. The game works on my other computer so it's not the disk. I've only really test one other game on my CD-ROM which is Diablo 3, it works perfectly fine. Here are my computer specs: Windows 7 AMD 6100 sic core processor 3.30GHz 16 gigabits RAM 64-bit operating system NVIDIA GeForce GTX 670 DVD/CD-ROM HL-DT-ST DVDRAM GH24NS90 SATA CdRom Device
