Bought ADZS-21569-EZKIT, CCES License nowhere to be found

So according to Analog Device websites:

www.analog.com/.../adswt-cces.html

https://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/ADZS-21569-EZKIT.html 

Our newly bought ADZS-21569-EZKIT should have a  free CrossCore® Embedded Studio License,further researching on ADI website,the license is activated using the S/N number that comes with the EZKIT. I searched the EZKIT package (bought from Digi-Key), no S/N number found. Can somebody find me my free license or give me my S/N number? Much appreciated.
