Ok, I uninstalled 4.16.3, and redownloaded the file(I had deleted the install file from my desktop). I still didnt have a preferences folder nor the gnutella file, but the brickwall is gone now(by the way, I was able to upload when I had the brickwall after installing 4.16.3).

I have since uninstalled 4.16.3 the 2nd time, and installed 4.17 beta now(no preferences folder or gnutella file), and brickwall is gone as well. I will leave it running & see if any uploads happen.

By the way, the only file I can find to download/install is LimeWireWin(~4mb) which I get when clicking on either the Get Basic button or the 4.17 Beta button. I tried cancelling it as you said, but was no other option to download anything. Is the file I should be getting?
