Validating the Steam cache? I believe that was in the link the support manager provided. I did try that, and I also just re-did it in the hopes it would take, but it did not. Sad face.
I hope I don't sound argumentative, I really want this to work so I can get back to playing (errr, testing I mean!).
The ticket number is #XLS-970-64877.
Both the Yor and the Drengin have been rather unfriendly. It just makes it that much more fun to crush them. As a side note, the declaration of war from the Yor is one of my favorite dialogues so far.
