How to register your Total CMS license?

When you purchase Total CMS, you will be emailed a serial number in an invoice.
Inside the project file for your website there is a Register CMS button inside the Admin Core stack.
Click that button and enter in your serial number.
Preview your page and a registration window will appear.
Verify that the information in this window is correct.
Click the Register button.
You can now turn off the Register CMS button in Edit Mode.
