You've left out some important details.

What is the brand & model of your modem/router (the firewall that LW detects might be within your router)?
Where are you connecting from (house, appartment complex etc)?
What version of LW are you using?

After using the basic version & upgrading to the Pro version, it's always a good idea to do the following:
Delete LW's preferences folder when LW's properly closed. See point 3 here & also point 2 if you've used older versions of LW in the past (there could be a folder in either location).

This will kill all of your settings within options, you'll have to go back through afterwards & reset things. If you're not sure of your settings, go through LW's tools > options & write them all down, so that you can reset things later.
