[otrs] Don't See AdminArea Icon

I recently logged in today with the same user I've been logging in as that has Admin rights and I now can't see the "AdminArea" Tab? I went to my preferences and under the custom queues I saw that I don't have the stats, users, junk, raw etc. queues available. Somehow I locked myself out of the AdminArea. This happened to the other agents who have access to the AdminArea as well, so I'm guessing it's over all of OTRS. Any ideas on what I could have done and how do I regain access? thanks marshall
