Unable to activate

I downloaded a copy of Morpheus 1/13/07 and also bought a backup CD copy which I received a few days later. Every time I try to activate my copy using my activation number I get an error message saying I have to be online to active, and that I should turn off all virus stuff/firewall etc. I have had our organizational IT guys in my office turn everything off and I'm still getting the message. The FAQ mentions port 80 which is all ok accoring to our IT guys.
Please help - this is more than a little frustrating.
