Just recently installed LimeWire. Went for a few files and they downloaded in seconds, I was quite impressed. Started going for more and since then they just connect and queue, maybe one actually starting to download. The speed sits at 1 or 2 KB/s and shows over an hour to download the file..but my connection icon in the bottom shows full green bars. I haven't changed settings since first downloading LW and getting those first files in under 30 seconds, what has happened?

(running windows XP home, if it matters.)
