Entering Your License Key
 
Launch NoteBook, and after reading and agreeing to the Software License Agreement, enter your NoteBook license key.  If you purchased NoteBook from a store, your license key is located on the back of the CD envelope.  If you obtained NoteBook over the web, your license key will arrive in an e-mail from the Circus Ponies website.

IMPORTANT: NoteBook 3.0 license keys are case-sensitive.
After you enter your license key, NoteBook saves it in a file in ~/Library/Application Support/NoteBook/Licenses.  The next time you launch NoteBook, it will read your license information from this file instead of asking you for it.
 
 
NOTES

If you’re upgrading from an older version of NoteBook, you can’t use your old NoteBook license key to run NoteBook 3.0.  Please visit the Circus Ponies Online Store to purchase a license key upgrade.

Store your NoteBook license key in a safe place, in case you ever need it to reinstall or relicense the application.  Don’t store it in a Notebook — if you can’t launch NoteBook because you need your license key, you won’t be able to retrieve it from within a Notebook!
