I have looked as much as I can stand, trying to find out what could be causing the issue, but so far, not one of the DLC's will load.
Running Windows 7 64 Bit
All Drivers Current
Can play the General Story line fine, but Not one of the DLC's will load. Not sure what is causing the confliction.

Figured it Out. Patch 1.7 is useless, It allows the level cap increase, but doesnt tell you. It also does not allow access to any of the DLC's entrances or content

So basically, Roll Back to previous patch

Okay, so only two of four loaded. This is getting tiresome, I mean really. whats to point in spending money on a game if the *censor* thing doesnt work? I was able to get Dead Money and Honest Hearts, but not Old World Blues or Lonesome Road, both of which i have been anticipating for some time now.
