Character stuck in corner

[GrandSpleen]

This is a technical problem but not a hardware issue.

My character has become stuck in a corner of the wine cellar, in a crouched position between a wine shelf and the wall. I'd really like to be able to free him without starting the game from scratch. The game has been saved, and when I load it up he is in the same, stuck position. No amount of wiggling seems to be able to free him.

Is there a debug/no clip code to get me free, or some sort of unstuck command? Or a way to roll back to an older save?

Thanks for any help,
GS

EDIT: I've seen other posts referring to "load an older save." The only way I have been saving the game is to save & quit when I'm finished playing (as per the game's suggestion on first booting up). I didn't even know there was another way to save it (so I didn't realize you could even get alternate saves...). But then, I haven't been looking for it. Or is there a different way to load "old" saves?
