Authentication Failed.

Got all downloaded last night. Got my key and all that.
Then when i got the demonbuddy launcher and try to log in:

Logging in...

Max Sessions
Authentication Failed.

Does anyone have any known fixes for this? If so thank you in advance.

I have now realised that when i first open the launcher. It lets me log in. But it then comes up with demonbuddy has stopped working.

Then when i reopen it. I then cant login because it says max sessions.
