I’ve purchased 1973.
I’ve put the product key in the same directory (“Folder” as I’m on a Mac running 10.6.2).
When I load 1973 (in Logic 9.02) I still get the message/screen saying I should purchase and authorise the plugin (or whatever it actually says).
The au component and product key are in the following directory:
The email that sent me the download key says the key is called xxxxx1973.key (I have replaced the 5 digits with x).
I notice that in the directory the key appears as xxxxx1973.key.txt
The same applies to Rocket which I have purchased
