This has to be by far the glitchiest game I've ever played.... It won't load for me, I start the game and it stays on the loading screen, I believe it's do to me being in Red rock canyon (Great Khan's main area). Just won't load... I've downloaded DLC for this game, $20 worth which is kind of alot, especially for this glitchy as hell game. Not to mention the constant freezing and black screen I get from leaving the Hoover Dam offices... I don't care how old this game is, it needs patched and have the ability to be played.

How doesn't it load...
- Does the console freeze (on the loading screen)
or
-Is the game constantly loading (continued loading screen)

If the later is case:
Start a new game..
As soon as you wake up : press start and load your savegame.. It should now load normally..

As for freezing clear both the system as well as the software cash.

and
Right when the game starts to boot up, hold LB+RB+X. Keep holding that until the Bethesda logo disappears.

Many thanks Thorgal - you 'new game' suggestion worked for me

Now back to Black Mountain...
