ok if using windows: in your control panel, go to network connects, and it should tell you if your windows firewall is enabled or disabled, disable it while downloading, then turn it back on after you are done using Limewire, you can right click, bring up properties and uncheck it to turn it off, then double check all your Limewire settings for uploading, downloading and sharing. Limewire sets everything as default, but you can always make adjustments. also, it could be they haven't discovered you yet, give it sometime. if you still have no uploading activity, it could just be the network acting up and has nothing to do with your end. once school startsup, all the freeloaders will be back on their school computers dling.
