How to I buy two copies of the game?

I attempted to buy a 2nd copy of the game, but I get a message that I have to wait for my order to be processed:

Order number: 3480916
Status: This order has been queued for processing by customer service. You will receive an email within one business day, at which time you will be charged and your order will be fulfilled.

So I just activated the one copy of the game I was able to buy on my son's computer, and the game will not run.  Steam does not give a useful error message.  After launching the Servo.exe manually I get this error:

"The version of this file is not compatible with the version of Windows you are running.  Check your computer's system information to see whether an 32-bit or 64-bit version of the program."

This computer is running Windows 7 32-bit.  Is Servo 64-bit only?  I specifically checked your website to make sure this older computer would be compatible, and I did not find any information stating 64-bit required.  In addition, the FAQ says it will run on older systems but will use the newer hardware if available.

Am I hosed?

Sorry Gank - wish I could help you.  I did share this link with a Stardockian in hopes of getting it sorted out.

It certainly should not require 64 bit. We'll figure it out. Work with SD support to get us all the info, please.

I submitted a ticket with a log file.  Thank you.

Well, it turns out I am incorrect. We are 64 bit only ATM.

Thanks for the info.  That explains it.  Guess I need to get this computer into the modern era then.

Gank - I've responded to your ticket. Just let me know what you'd like to do in your response in the ticket.

p.s. I think it's super great you want to co-op with your kid!
