We received our retail copies this afternoon and after bit of effort, managed to get them all packed up and sent out via the US Postal service (not overnight shipping though
.
Everyone who had a CD pre-order through Stardock as of around 1pm today should have had their copies shipped out. As everyone in that category has a serial number, you can use Stardock Central to download and install the latest version of the game (even more recent than the retail CD). Same goes for TotalGaming.net customers (though you didn't have CD's sent out).
New CD orders as of this afternoon will not include the ability to download immediately, you'll have to purchase a TotalGaming.net subscription for that. They will however include a download link and serial number for the Political Operatives Kit. Once you've installed from the CD, download that to add the editors to your install.
For direct orders from Stardock, https://www.stardock.com/support can be used to resend the latest download information and serial numbers (if applicable) for your order.
