404 Page Not Found

Hi everyone,

I hope you can help me. I installed VibeStreamer and also activated the portforwarding at my D-'Link Router. I will only use VibeStreamer from within the network. Everytime I try to access VibeStreamer through my Netbook within my Wireless LAN, I can get to the log-in page, but after entering the username and password, I get a 404 - Page not Found. On the host pc, I can see that the user has logged in. So where´s (my) the mistake?

PS Now I get 403 Forbidden - Server is full after trying to log in.
