I have Limewire 5.5 (newest ver) and am running it on Window 2000 Pro. I am able to d/l with no problems. When others try to upload from me it just sits there saying uploading but going nowhere until the other user finally stops the u/l. I do not have a firewall, virus protect prog., and the bandwith is set at max. with 6 total uploads available (3 per person). Thanks
