Slitherine

I just applied the 1.3.85 update (successful), but I cannot for the life of me find the place where I enter the serial number to unlock it. All the prior DLCs (Sin, Anabassis, etc) show up, but when I click New Game the Resurrection option is greyed out with a Locked icon.

purchased the game on Slitherine site and I have the serial key, just can't find where to enter it so I can play!!!

Support site is just hanging and wont respond.

where multi keys / DLC's are used, maybe this one

Normally one does get a screen like that in the BSG installer/update to add serial keys. It's missing from this DLC. I tried using both the 1.3.85 full download, the Check for Updates function in the game launcher, and the small Resurrection installer on the Slitherine website.

It's not in any of them.

Download the installer file from Resurrection from the Member's Area (or any of the other DLC if you want to install them) and run it to activate the game.
