search returns results, can't download nothing..

[asebest]

hi.

since a certain moment, i can't download a thing from limewire. i've tried pro and basic as well. it's not a firewall problem for sure.
the search results are appearing normally, when i'm trying to download a file it's impossible (i've downloaded nothing since 3 days). limewire is connecting to the host for a couple of secs or mins, than just waiting for more sources and there is nothing i can do..
Thx for some hints.
