I think most of the "can't connect" problems aren't our fault. Our bootstrap server, router.limewire.com, has been running flawlessly for weeks now. Often when someone can't connect, it's because their ISP is blocking outgoing connections to port 6346, the Gnutella default. Try telnetting to router.limewire.com port 6346. If you don't see "GNUTELLA OK", holler at your ISP; there's nothing we can do.
