I think this is a known Bug which happened when the new IPB TopList was installed. I believe the Staff know about this error, and I think for some it has been fixed, and other's not. Wait for another member of staff, either Toxikk, Timdorr or Sietse or any of the Administrators and I am sure they can work something out. Most likely they will mark this an an open bug message.

Hope this helps, and a tip, don't keep bumping your threads if you don't get an immediate response.
