You don’t need to uninstall to move bbPress as such, since it’s not installed in any way apart from the the .htaccess file settings and the database settings.

You need to change the uri setting under bb_meta in the database to the new forum URL, and then change the .htaccess file so it matches the new directory.

The .htaccess file can probably be fixed by turning off Permalinks and then back on. Don’t forget to log out and in again too.

The options might be changeable by using __ck__’s All Options, but I have a feeling the URI isn’t editable from there.
