It sounds like I'm having the same exact problem. I've had Vista for over a year and LW connected with no problems till about a couple of months ago. Now, I open it and it says it's connectign and never does, I have also tried everything as far as uninstalling and reinstalling then I just recently switched to LW Pro and it still doesn't connect, I have also tried going back to all of the default settings, going into my computer settings and trying things there, and messing with my firewall configs and still nothing!!
Can someone please help those of us with similair problems?
I think it would be greatly appreciated by all of us!!
