"This player does not exist"[fixed]

[franzi_nator]

Today I wanted to play Shootmania but ManiaPlanet refused to login and said that I wouldn't have access to the Internet.
So I tried to login at player.maniaplanet.com and after trying it says "This player does not exist".
What should I do? And whats about the beta? Just because I had 5 days left but I wasn't able to play it today (and I'm not sure if I can play it in future with my account )

Thanks in advance

Update: My boyfriend tried to login with my account - with success? wth?

Update²: Problem solved. I had to deactivate my LAN-connection (I'm using WLAN) and that's it. :<
