Can't update the AMS.

Hello,

We are testing the demo version in our company but seems that we are not able to update the virus deffinitions in the AMS. I have tried going to the avast program in add/remove programs in control panel and I am able to verify the connections but when I check for updates it says that I have the latest updates. As of the moment We have 080807 definitions basically a week old.
We have opened the ports in the firewall and verified that it communicates with the avast servers. Any Ideas?!! I included some screen shots trying to update.
