I've had the demo version (or whatever you want to call it) of Lime Wire for a few weeks now, and I've only been able to dowload a couple of comedy mp3s. Everything else makes an attempt to connect, but then I get the message that says "requery sent, waiting "x" amount of seconds." What is the problem????

The requery is a long shot, it rarely results in a successful download except when the file is extremely common on the network. Just enter the search term again, and find yourself a new version of the file. If you can find an identical copy, it will even resume your download.
