Limewire connecting and dloading fine, but i feel bad that no-one can upload (even though i am sharing plenty of files).

I think i have done everything i should to stop the windows firewall blocking Limewire, including opening specific ports (and even just turning it off for a while), but the tools-options-bug check thing still says false and there are still no uploads.

Is this because I am on a home LAN and this pc goes through a wireless router, then another pc, then an ADSL modem to get to the internet? (this was the problem with WinMX, and why i gave up on it in the end).

XP, SP2, only windows firewall.

If there is a simple solution, then i'd be grateful.
