I have the same problem!!! LW was working for me GREAT until I had to reformat my HD

. I acctualy did it twice to make sure that it was not the windows install that was causing the problem!! I downloaded Java Sun from their web site, reinstalled that about 3 times as well as LW! I have NIS and a router but I know how to configure those to connect to LW...hence working GREAT before the format!!
Basicly the two times I did reformat, I did manage to get to the LW start up screen and then it just frose...after that I can only get the hour-glass for a second and thats it!!! Here is my Specs:
Windows XP SP1 (don't like SP2)
NIS and Router firewalls
1024mb RAM
27.6GB Free Disk Space
High Spee Lite (a little faster than dial-up)
Router: SMC 7004WBR
Trying to connect from Home
LW ver. 4.8.1 w/ Java Sun 5.0 Update 2
ISP: Shaw Cable
And this is a new problem, I would like to say that I'm a experienced user!!
I hope someone can help?!
thx
Dan
