to further complicate matters:

i tried the test on my connection and i didn't get a GNUTELLA OK either, but i have limewire running and it works perfectly fine (i'm not with comcast).

if i get nmaxfield's post right it stopped working right after installing 3.0.2? it seems unlikely that they would choose that moment to start blocking gnutella.

did you update from a very old version of limewire?
