BBCode won't work on actual pages or blog-posts

I just installed the BBCode, and when I edit a blogpost or page, and view the post in "Rich Text Format" Everything looks okay for the bbcode, but after saving and viewing the real draft or published content, the bbcode is just raw, showing the whole thing in the page as [url=sfsdf] etc...

Any ideas what is up?

and I mean I'm using just the 7.x-1.0 not the 7.x-1.0-dev
