Hello All,
Yesterday I started FSX:SE and selected my 737-700 winglets model. When it loaded, a screen popped up and said that I didn't activate my PMDG yet. I did not torrent this, I clearly bought it but It's saying that I have to "activate" it. 
Thanks for your help

Here is what the image said:

" Your PMDG 737NGX Base Package is not activated yet. Please select and activate a PMDG 737-800NGX or 737-900NGX variant first. Note that there are separate product keys for the 800/900 Base Package and the 600/700 extenstion package. Please make sure to use the correct key. The simulation will now exit."

 

I have never had a problem with PMDG and FSX:SE until now...

You did activate your 800 model first? This is the base package.

Without this 800 package, the 700 cannot be used,

I am pretty sure I did activate it but If I didn't by any chance how do I activate it? Where do I find the place to put the activation key?

Thank you for helping

KH

Start a flight with the 800 again. It will tell you if it's not activated by giving you a popup.

You will also see the correct displays on the NGX.
