Pretty much all my games are Steam now. Have DCS and most of the DCS DLC on Steam.
As DCS WWII Kickstarter backer ($100), I have 5 aircraft coming. I selected FW190 and got a serial number -- on the "backer's" page.
Now, this site says the serial numbers I get here will not work on Steam. Not good.
Is there a way to activate the DCS WWII FW190 on Steam using the serial number I got as a result of backing DCS WWII Kickstarter for $100?
