Bought P51 from steam, serial number not working in standalone

[dikkeduif]

I bought the P51 on steam.

I have the standalone version of DCS world and I want to use my steam P51 key in standalone.

 

When I enter the serial number, the key is not recognized as being valid.

Make sure the Activation Box says P-51 in the title bar,

 

also make sure you are entering the whole license key, some people had that issue, they'd click "View CD Key" and type in the number, but it goes past the end of the CD Key Window,

 

Copy CD key to Clipboard, then Paste usually works better.

Hi Skatezilla.

I was trying to fill in the cd key for the p51 in the box for MI8 activation. I was a bit confused because I tried to start a P51 mission and not a MI8 mission, so I was convinced I had to fill in the P51 key :)

 

Many thanks! Problem solved
