Freezone Server "Already paid"

[Bas3008]

Hello,

I recently tried to delete my freezone server on the manialink "freezone:servers" due to a failed transaction. Then some weird error popped up while I tried to delete it (something like "Couldn't register player login" or so) and now the server is still registered, but I got the 10000 Coppers back. So if I try to delete it now, there's a message "Already paid", what seems to be correct, but I also can't add my server again.
Any suggestions or help?

Greetings,
