as I said, LimeWire keeps disconnecting on me when I'm downloading/searching. Is this because of the fact that I have a modem connection or is there a problem with the server?

Not only is it disconnecting ever five minutes, the files that were being downloaded restart from zero, not from the point at which they disconnected. And on top of this entire ordeal, I can't save my preferences. Everytime I disconnect, the Options revert back to their original settings. What gives? Sheesh!
