do you run a firewall/router combo? if so, do you have 6346/tcp open for limewire? has limewire ever been installed on your computer? if so, 6346/tcp would already be open.


if you believe its something you did, go to Tools -> Options. find the button near the bottom that says "Restore to Defaults". click that. if it was a box or something that messed you up from downloading, restoring to defaults will fix that.
