Yesterday everything was fine, but today, when trying to go into aikido1 (or any room, i tried it.) this happened:

I have already reinstalled it, it keeps on happening. i have logged out and in again, too.
In case it influences it, i use a Windows XP.

Any help is appreciated, thanks in advance.

Maybe your belt isn't right for the server. Have you tried green belt or brownbelt servers?

I'm orange, and sorry, didn't know belts influenced it. let me try.

EDIT: yes, it worked. thank you.
