When I go into the DLC purchase screen, nothing is recognized as installed (not sure if it is supposed to). I've been able to finish Captain Scarlett's anyway, but I don't see the Fast Travel location for Mr. Torgue.
After looking around a bit I saw that there were some problems with the disk, but I wasn't sure if they have been resolved yet.
Tried re-installing from the disk, clearing cache. --- 8.617 x 10^-5 eV*K^-1
