I had the same problem as many here my lime wire pro was not connecting. And if on the odd occassion it would it would soon disconnect. I gave up and installed Bear instead.
Then to my surprise I went back to lime wire. When it asked if I wanted to make lime wire my defult i said no. Since then I have had lime wire going all through the night and it has remained on connection in turbo.
I later said yes to make it my defult and the same connection problems returned. SO again I said no and have had no problems since.
I too before hand had tried everything suggested here. So I hope my surprise find helps others
Good luck and happy searching
