cant download from limewire or .torrents either for some reason, i can download for example a file off of limewires' site and it works, and can use the internet at good speeds, and my computer is virus free, but limewire will not connect for some odd reason. it worked a few days ago and there have been no changes to the network config anytime recently. i realize that i have java v 1.5 and 1.6 is available but it worked with it earlier so im a bit confused. the file directory to which im attempting to download to is valid, and the port through which im attempting to download through is open. i have full green bars on the bottom left, searches complete, downloads try to connect and then say need more sources, but the downloads im attempting have 80+ users sharing it and are on the top of the list when sorting by # and availability. i have read other forum listings on connection issues and no answers seem to apply to me. i have windows firewall disabled and norton enabled and it states full access priveleges for limewire, and limewire still does not work even after i disable that. ive tried restarting my computer, restarting limewire, repairing internet connection, turning off and back on my modem/router because sometimes it glitches, nothing has worked. what other issue possibilities are there? thanks for your time
