Haven't used FsPassengersX for a long while, came back, says I need to purchase.

Title explains it pretty well; It has been a long time since I last did a flight using FSPX and just the other night I went to fly it again and it tells
me I need to purchase and unlock the full version. I haven't really a clue where to start, could someone help me out?

Have you tried using the unlock code you purchased lo those many years ago?

[MaximusPaticus]

Negative. I'll have a look in my email history and try to spot it. Is there a way I can post something from FSPX that would prove I have it or
bought it?

After a good bit of digging I found the key-code thingy in my email, punched it in to FSPX and it worked.

Thanks.
