Classified link does not redirect

Just installed the classfied plug in on my newspaper site as I am hoping it can be used to handle all our needs.

I was expecting a little more front end thing with categories and such for the main page and it may be there or require more work so I won't complain about that yet.

I have two things going on currently.

1. on the user profile page when you click on classifieds it goes no where. See the screenshot.

2. On the main page when you click on an ad it brings of a sorry page can't be found error.

How do I fix these?

Any other insite or examples of current sites using this would be helpful. Or if there is a better solution than this plugin to use please advise on that as well. Thank you.
