Lets start with a few questions.
1) Has this device ever worked successfully since installation?
2) If it has, then have you changed the profile?
3) If not, have you tried uninstalling the WCG software, then reinstalling it?
4) Did you accept the default profile, or did you create your own?
5) What sort of security programs (firewall / anti-virus) do you have?
6) Is there a router on yor connection?
7) Is there a message on the WCG Agent if you click on the icon to maximize it?
8) Have you read the Trobleshooting pages in the FAQs?

Sorry if this seems like an inquisition, but please give us some additional information.

Curiously,
Lawrence
