Ambrosia has a autkey recovery on their support site - great service. Thx for your help

Heya, I lost my key for Defcon after my mac hd crashed. I bought Defcon online, so I tried to find the email with the key, but I couldn´t. Defcon is still installed on the old harddisk. The files on the crashed HD are still alive, so is there a file, where my key is recorded? Thanx for your help DaDan
