The trial mode ones are only ones that I have not purchased yet but have them installed to see what they are like.The ones causing problems are all purchased airports
This is normal then. There's no difference between purchased airports, they are all requiring a reactivation now, it wasn't entirely clear from your previous messages.
But in this case, it shouldn't be a problem just confirming the reactivation message when they appear. There's no reason the activation won't stay UNLESS your user account has limited permissions, or your are running FSX or any of its add-ons into a "Compatibility"mode.
I also moved parts of my user profile from my ssd drive to the hybrid drive to save space ie the my documents, my pictures etc.
Impossible to help you without knowing EXACTLY what you did, you just can't move all files freely from an user account to another one, when migrating to a new drive there are plenty of things to consider, like file system permissions, registry permissions, etc.
In any case, the Serial Number is stored in your USER registry so, whenever you create a new user account, you will have to re-register the scenery, even if this won't count as a new activation ( if you haven't changed hardware or reinstalled Windows )
