11.04 - I lost my top left panel in unity. How can I get it back?

How do I reset my Unity configuration?

I messed around with the compiz setting to set up desktop cube when I first installed 11.04. Big mistake right? I have everything back to normal but my top left panel is gone and I have tried everything to get it back. Unity --reset usually hangs on me and nothing else I have seen in the forums works.
