I am running windows XP with a DSL connection,

The problem I am having is when a download "needs more sources" and I re-search, I still cannot get the downloads to resume. I can find the same files, some times with 20+ results, but cannot get the downloads to resume. the same is true with the "awaiting sources" status. Sometimes it will show the file download icon in the quality listing, but nothing happens.
Sometimes if I shut down Lime Wire and restart it, it works fine and my downloads continue, other times I get the "could not load old downloads" error message.
I don't like shutting LW down, as it breaks the connection for people uploading from me, but I want my downloads too....

What to do????
