How is this possible ?

[Robert the Bruce]

Limewire Pro tells me that 'your machine does not appear to have an active Internet Connection or a Firewall is blocking Limewire from accessing the Internet'.
However, I'm able to access Google, surf the net and post on this forum.
There is no 'brick-wall' icon next to the 'globe' icon on Limewire Pro's page, I have 'allow full access' regarding Limewire on my security system and my monitor icon on the taskbar says 'status-connected'. So anyone have any thoughts on what's wrong here ?
Edit - downloaded 'purger .zip' but everything happened so quickly I don't know where it went, did a search, no results, so where could it be ?
I've read the sticky and believe my ISP does not block Limewire since I have downloaded tons of stuff in the past without problems.
More info - Modem in living room - Wireless Router near Modem - Computer at the other end of the house in bedroom (about 20 feet away).
Problems like this with Limewire are intermittent.
A wee bit more - in the sticky 'for those who can't connect' when you say 'delete the entire directory' do you mean delete the limewire folder within 'Documents & Settings' ? How will Limewire run without that folder ?
