I'm having the same problem. The weird thing is I share a computer with my son -we can log off and on, changing users. When I'm logged on and using LimeWire, it downloads songs just fine but when my son logs on and opens his LW, the downloads don't work. Is there anyone out there who might know what the problem is? In comparing the two LW sessions I've noticed the green circle down on the lower left corner next to the firewall icon (the globe) has a "0" in it during his session where he can't download, whereas during my session where I'm able to download there is a # in the green circle -specifically "255".
