So, my girlfriend and I both got hard copies of the game. Both disks work fine in her computer, but both disks fail in mine... the drive starts clicking and will not read the disks.
Now, before you say that my dvd-rom is failing - I tried many, many other disks. Everything from games to music cds to DVD movies... everything works fine in my drive. I assume that there is a manufacturing flaw in the disk, but it is minor, and some drives wont detect it, but some will.. maybe my drive is more precise or something.
Anyway, what you can do is get steam (if you don't already have it) and go to Games > Activate game on steam, and put in your CD key... it'll download and install without needing the actual media. You can also put in any preorder key in the same way.
