Serial ID for new planes?

[Gonzxor3]

I bought the A-10 a long time ago. I know forget what steps you must do to unlock the plane.

 

I just bought the F-15, I got a serial number. My question is, how do I give the serial code so I get the plane? The F-15 alone is not a module on the main menu screen either. Sooo... Im confused.

 

Thanks -Gonzxor

It's been a while since I last activated any of my modules, but IIRC, just play any mission with your newly bought F-15, and a window show automatically appear asking for your serial code. Just enter it here and you should be good to go!

It should be, on my screen theres an icon labeled "F-15C Beta" (I own FC3).

As said just start a mission with F-15C and it should ask you for a serial code. You can also open the module manager and enter it there (thats the correct place for all your module managements :D)
