Hi! Cant help you with your problem..but since I have almost the same problem as you, I will put it in here...

my LimeWire works just fine..BUT, the main problem is that I cant download any songs, or any files for that matter..no matter what I do it just wont download...I dont get any licence msg either..nothing happens..

if there is anyone out there that can help out, please share your thoughts... this is VERY frustrating...
