Banned From My Own Forum

Can anybody help me with this, I have just opened up my forum to find that I have been banned, this has confused me completely because I am the one and only administrator of the forum and therefore thought that only I could ban myself (which I did'nt of course).
Last night everything was fine with me being able to log on no problem, to see what I mean try this link [url=http]Here[/url].
Whats also bugging me is that it appears that I am still logged on, yet if I try to log out I can't the page just keeps redirecting back to the same page.
I am not sure if this problem has been caused by an hacker or if it's something to do with all the extra security IM has.
Any help would be greatly appreciated.
