Used Kazaa and LW2.8.6 at the same time - no problem.
Got the message to update and like an idiot I did.

Could not connect at all until I surfed these pages and worked it out.

Disconnected Kazaa and I had no problem connecting. Seems Kazaa and LW3.0.2 both use port 6346

Pity, double downloading is better, especially PC and Mac apps
