I’ve installed bbPress 0.9.0.1 in a WordPress 2.5 site. It works for a while then when I try to access a topic I get:

Not Found

Sorry, but you are looking for something that isn’t here.

and the theme displayed is that of the WordPress blog. After that, only the bbPress front page is useable.

Further to this, it happens when I change the permalinks to Pretty permalinks, name-based. Seems that change doesn’t take effect. Changing the permalinks back to None corrects the problem.

So I wrote Options +MultiViews into an .htaccess file in bbPress root directory and that fixed it.

RTFD!
