Okay my account is back now.
Thank you!

Yes and it says that my login is wrong.
But it's 100% the correct login. I've even checked the login in the log of my server and it's 100% correct.

Hello, I hope i'm right here for that issue. I guess nadeo banned my maniaplanet account. Today i was a bit too angry and changed my nickname to "Fuck you *" and a bit later as i wanted to log in the game again, the account didn't exist anymore. It disappeard from the login screen in mania...
