cant connect to gnutellahosts??

Ok I have used gnotella for a few months now and it worked like a charm (well almost) for all the time I was at school. I came home and Gnutella seemed to work on our shared cable modem...anyway we get a router for us and nothing else seems to change and as far as I remember Gnotella kept working then. Then it comes with a message that says I should update, I was pretty sure I had the latest version but what the hell so I updated it but I realized that it gave me the same version and just put it in another directory. Since then every single time I open it it says I need to upgrade to the latest version and on top of that I can no longer connect to any of the gnutella hosts. It sucks now I have to use audiogalaxy...
