Hi there. I suggest you drop a line to the admin here who deal with this sort of thing.
[email protected] Might be a while for them to get back to you, but defo drop them a line to see what has caused this problem.
Do you use a shared PC at all? Could be simply a case of some one not logging out. Also try clearing you cache/cookies etc and trying again then. Log off and log back on again.
Let us know how you get on.
(Sorry Ev' for hijacking this for you...)
