what happens after fsp purchase?

[modes4284]

I recently purchased fspassengers off this website and now I am completely confused on what im supposed to
do. I got my unlock code
in my email address but i dont understand where i need to use it. Do I get sent a copy of fspassengers or do i
have to download it off the
website? So after much frustration i downloaded the free version hoping to be able to unlock the system from
there and i had no luck.
What do i do? PLEASE HELP!!!

Download the file from the FsP website (26Mb or so) and install it into FS, then having gone into a flight in the normal way go to the FsP
menu and near the bottom will be an 'register fsp' option or similar. It's the same file as the demo, but with the unlock code it removes the
demo restrictions.
