Connection problem with AB3

[Adept]

I've recently upgraded to AB3, and last night purchased a licence over the internet. When I went to activate my licence, my copy of AB3 got to the last stage (having entered the licence code, my name, email and postcode) and AB asked me to establish an internet connection.

I did this (I am on dial-up) and hit next.

I got the following message:

"An unexpected error occured during the processing of your licence. This often occurs when the internet connection is not properly established, or the Lone Wolf Development server is not currently reachable. Please re-check your internet connection and attempt to access your licence again in a little while. If the problem persists for an extended period, please contact Lone Wolf Development at support@wolflair.com for further assistance"

Now, I'm pretty sure there is nothing wrong with either my connection or the Wolflair site, and the error message flashes up almost immediately rather than waiting for 30-60 seconds like it should. This leads me to believe that for some reason my copy of AB3 is not recognising my internet connection.

I'm really hoping someone can shed some light on this!

EDIT: I've tried this with my firewall and pop-up blockers turned off, and I've added AB to exception lists for both, but with no success. Are there any other programs that would prevent AB from connecting?
