i have to go into the black briar lodge (i have to get stone of Barenziah), but after i have clicked A button, xbox 360 freezes (from any doors of black briar lodge).

solutions?

tenx a lot

*UPDATE*

First look up the problem in Google, just in case it's somehow related to that particular building.

Load the last save.

If that doesn't work, load the one before it.

Or

Clear cache.

Or

Uninstall and reinstall game.

Or

Clean disk carefully.

It could also be that you have too many saves.

This can cause the game to freeze, especially when it has to make a new save file.

Although it seems to happen less nowadays.

If you have over 600 saves and none of the above methods work, delete some save files.

I keep the last 10-15 saves. Disable auto save and only use manual saves. You can also clear the system and game cache.
