If you are having the “Missing a valid product key” / “Enter your Product Key” or
“Can’t Sign in because your product Key is not Valid. Please Enter a Valid Product Key” errors
We have a solution:
To find and enter the LIVE access code:
Exit Age of Empires Online
Go to start --> Programs --> Microsoft Games for Windows Marketplace Client and launch the GFWL Marketplace Client.
Sign into the marketplace client with your LIVE username / pass (Same as you use to sign into the game).
Navigate to the Download Tab
Select “Age of Empires Online”
Click “View Game Keys”
Write down the LIVE access code.
Launch Age of Empires Online and, when you receive the error simply press “Try Again” and enter the LIVE access code in the space required.
