Elemental: Fallen Enchantress Registration (Network error)

I purchased Elemental: Fallen Enchantress as a one-time purchase through Steam.  I created and validated my Stardock account in order to register the game, however when I attempt to register it I get the error message:

"The activation program could not communicate with the server.

This may be caused by a firewall blocking Internet access, please check your settings and network permissions."

I disabled ZoneAlarm, AVG antivirus, and Windows SmartScreen.  I also bypassed my router and plugged directly into my cable modem. 

This was all to no avail.  Then I signed in to this site and went to Account Management (https://www.stardock.com/accounts/register)

I could not find my game in the drop-down list of products to register.

I am not a network whiz, nor a Windows expert, so I'm really not sure what else could be blocking the connection.  I am running Windows 8 and for security I have the 3 things I already mentioned, router (that I bypassed) and ZoneAlarm and AVG.  I haven't installed any other network security software.

Also, I tried activating on multiple computers using the .txt file, and here is the message I got:

Incorrect email or password. Please ensure that you are activating with the current account credentials associated with this product.

Any assistance would be appreciated.
