Can't log in

Hi guys.

I need some help. Lately, I'm unable to enter my server.

Of course, I use smartftp to upload my files, and Macromedia Dreamweaver to create my homepage.
Until now, everything has worked just fine, but now, I get this message:
"Can't login because the target machine denied the login" (something like this, 'cause the original message was in Norwegian)
It tries to login automatically one time after the other, and it gets denied every time.

Help me please?

Tnx,

I suggest that you restart you pc first and then try again..

Because one time i had some sort of message like yours but then that your Host Machina actively rejected your connection and then i rebooted my computer and then it worked again..
