How do I use EAGLE light license?

I decided to purchase the EAGLE light since I'm gonna make a few bucks on the Phi-1 shield soon. I purchased the light version simply because I'm not crazy rich for the full version. But I found there's no place to enter the S/N code I received after payment.

Can anyone help? Thanks

BTW, here's my shield for sale soon:

My main window has "Eagle License..." under the Help tab, but mine is already licensed, so you might have something slightly different there.

Is your EAGLE a standard version or something? I downloaded my version from cadsoft.

With ONLY the "Eagle Control Panel" window open, select "Eagle Licenses" under the Help menu.

James, I tried. There are 4 options, none of which asks for an s/n: use license file, freemium, run as freeware, and cancel. Maybe I'm supposed to run the light version and just keep the S/N somewhere in case cadsoft is sueing my a** for not paying them while making money with my designs in EAGLE. ;D :o

When I click on "use license" I get this window, which allows for entering the installation code / serial number:

It asks for a file, which I don't have, and a code, which I don't know where to find. I recieved an s/n, which is too long and doesn't have 10 consecutive letters to fit the requirement. I tried and it didn't work. I'll call up the 1-800 number to find out. Thanks James.

Call me a dumb James, there is a second page besides the invoice. It details what to do. I'm kicking my butt right now. I'll need a printer as an Xmas present or move my wife's out of her home office.
