Yes. So now that I know the Key Code is the Product Code in essence I understand why I got kicked.
I'm using the iMac (DL from App Store). He's using PC (DL from Steam)
We deleted his using Steam, but we found out that the Key is stored in the Registry. We've deleted the Key from Registry and are trying one more install right now.
Our next step will be emailing Steam and begging for a Key. Unless you or someone else has any other suggestions.
BTW. I have recently been able to play on the Server, no problem.
