After I select a song from a search, it begins to download but only goes to 30-40%. I am then in limbo awaiting sources for ever. I also run into a "need sources" when I start the download. What causes this? I don't remember Napster or others I've used doing this. How can I correct this??

Perplexed......

Hmmm not sure, but think the programs you are refering to were on a central server. That is why they were shut down.

The Gnutella network is made of hosts/users not a central server, so if a host disconnects and they are the only one with that file you have 2 options.

1. Wait for the host to come back online.
2. Do a manual search for the file and try and locate another host with that file.
