this is probably what you mean. i had the same problem because i did not request the key when i downloaded the application. all you have to do is:
request the key:
you are required to enter your name and email address. then it will email you your key as an attachment.
then,
click on the small icon to the top left of the license key manager box (if you hover over it, it says “import license key” and import the .zvpl file that came with your automated email.
