As I suggested in the earlier post, there's a chance you have a protection utility which prevents your browser opening via LW. Do you have such a utility which might do this? And have you ever checked your computer with a spyware program that has said LW has spyware? There's many spyware programs out there that aren't designed to cope with p2p sharing programs & may do them damage. (They think magnet links are spywares.)

What happens when you try to do a Bitzi lookup? Did it work ok before?
