Hi Sara_also,
People have lives, be patient & someone will answer you

you need to give some details:
OS (Windows 2000, XP etc)
LW & Java version (in LW go to help > about LW & it will tell you)
Connection type (adsl, dial-up etc)
Modem/router brand & model number
Any firewalls you have running
Who is your ISP
Where you're connecting from ( home, school etc)
Have you used LW before, or is this your first go
What fixes you've tried that didn't work

have you read the stickies at the top of the page? If not, have a good look through them. There might be an answer there.
