How do I get the Q&A plugin to work?

I can't seem to find the page that this plugin is on. I read all the material but I can't get to the page. I have changed the permalinks settings as instructed and also am entering the link http://blackdogmastering.com/questions/ask/ but it is still not showing. Instead it keeps going to my unauthorized access page that was selected in the Q&A settings. Please help me figure this out, I am desperate and losing hope.

Thanks,
Andy
