No uploads is a different problem to 0KB/s uploads. The latter has been fixed in 2.6.3 of LimeWire.

The former is a different problem - almost certainly to do with your network rather than LimeWire per se.

XP has a built in firewall that may be causing problems (even if you don't think you have activated it).

Beyond that - I can't help much. I have to beat them off with a stick here.
