The initial purchase for KJFK V.2.0.0 was purchased from Simmarket, so I just went to the site and redownloaded a copy and installed it. V.2.5.2. was installed so I got the updated version during the install.
If with "the site", you mean Simmarket, you might not always get the latest version from there, since it might not be updated as often as the one on our site. The latest installer is always found on our site.
It didn't ask for a registration key
Our installers never ask for an activation key, because our installers are always a Trial version.
Not sure why I am getting the Trial Period message since I actually never installed the trial version it was always a purchased product
Yes, you DO have installed a Trial version. That's what all our installations are, before you activate them using the Addon Manager menu and your key.
Addon Manager had it as Installed and Active, I didn't have to do anything.
That's not because the purchase was verified on Simmarket, only because it was already activated on your system, and you never changed hardware from the last time it was activated on it.
Addon Manager had it as Installed and Active,
So, IT IS active.
It seems that the full scenery is installed (the scenery does not disappear after X mins)
Assuming you are looking at KJFK V2 ( there's a KJFK V1 too ), and it's reported as active, and you purchased JFK V2, and the scenery doesn't disappear, then you DO have the full version, and the Trial message seems to be bogus.
The most likely cause of a bogus Trial message ( but the scenery not disappearing and reported Active ) is another scenery for JFK in conflict that you have installed and not correctly removed.
