Two things I like to try when attempting to find a problem with bbPress is to:

Switch to a default bbPress theme, like twentyten.

Go to settings > Permalinks and update my permalinks again.

The second one fixes a few issues and the first one lets you know if it is a problem with your template, or a problem with your data.

Good luck!
