Attempted to install bioshock, the game installs and copies files, but when finished with that it then complains about needing to use the original disk and not a backup, click the button, and it then un-does everything it installed and exits. I bought the Limited Edition of Bioshock; figurine, 3 disks, and all, quite certain it is an original considering it is the one that came in the container. The inside ring of the disk contains a few sets of difficult to read numbers if you wish for them. One is: 21962-1V2L1; another is: 21962-1V2L0; another is: GI50201-L1; it also contains many bars of various shades and a couple icons that are too small to make out. Can take pictures and send as well if you wish. This system is well top of the line. So, why is it complaining about this when none of the other hundreds of game installation disks I have complain?
