Your LW use might be affected by ISP influence.

Try deleting your LW Preferences folder whilst LW is closed; instructions here: Point #2 & 3 in Fixes for Limewire (sample image included 2nd last post of page.)

I'd also suggest you update your LW ... http://www9.limewire.com/download/LimeWireWin-full.exe

I'm still having some problems getting my limewire to work. I've tried to do like you said in the instructions #2 & 3.. yet i couldn't find anything.. So i deleted limewire completely from my computer and am trying to re install and it keeps saying something about a win32 or something. It also has told me to obtain a new copy from the publisher.. but when i try to go from limewire.com to download it says the same thing. From download.com it does the same thing and for the link you've provided it tells me i am not authorized..
