SolidWorks Essentials 2016 Ebook Access Issue

Hi,

I have a copy of the 2016 SOLIDWORKS Essentials manual in my hands. I want to access the ebook so I can read off the computer.

There is a serial number on the inside cover of the book. I tried "registering" the book by typing this serial number into the "register a product" page linked through the SolidWorks customer portal after logging into my account. Unfortunately I get an error saying the serial number is too long, and that it should be between 16-24 characters.

How do I access my ebook using the serial number I have?

Thanks for your time,

Alex
