Hello - i had the same problem. no connection to any host - only a commercial provider and a clip host server - no others. then i tryed to add the "gnutella-again.hostscache.com" link and now it works - there are other hosts - try it! Perhaps there are any problems with the gnot-network?
Gnotella rules - "Filter"-Morpheus sucks...
