I have recently purchased the Dawnguard DLC, and have since been unable to play Skyrim at all. The game seems to function fine up until the point of where I try to load any save. My Xbox locks up every time during the loading screen with the tips present. I have tried every combination of reinstalling Dawnguard and clearing the cache without any meaningful successes. I can load all my saves without the DLC installed, so I know it has to be Dawnguard causing the lockups. I have also tried starting a new game. The game will start the intro sequence just fine, but then freezes before the carriage ride is complete.
If anyone knows any fixes for these issues please do share. I feel as if my $20 has been completely wasted and it is quite frustrating to say the least.
Thanks
