Thanks for the reply, sadly that did not work :/ I guess I'll just have to wait until a patch is released. Atleast I got to play the main story, I had to wait until the third patch for NV before it would let me out of the first town

Are you sure you did the cache cleaning and reinstall correctly? Clear the system cache on all storage devices, delete the patch, all Skyrim DLC and game if it is installed and then reinstall the game, download the patch and download all the DLC again. It worked for me when I got stuck in there with an endless loading screen, also cleared up a lot of other problems. They will not be releasing a patch, so you are going to have to get out of there yourself.
Also make sure all autosaving options are disabled if all that was not enough to get out.
And reverting back to an earlier save would at least let you continue playing the game.
