I have ordered a developer kit. Now I don't know how to activate it. I created an account in my sandbox, but it has no way for me to activate it. The instructions state to click Dev Kits on the side-nav, but as can be seen in the second image of the dashboard, there is no link called Dev kits. (2) Where can I find the serial number of the development kit? My Dev kit is completely blank and has no code printed anywhere.
