Unable to create Snaplex

I am currently using trial version of snaplogic registered with this mail id. And I am doing a POC for Snaplex on premise.

I was following the steps mentioned in the below link.

And when I go to the Snaplex I am not getting any option to create. The ‘+’ button is disabled. PFB the screenshot.

I need to know the reason behind it, Is it because I am using trial version? I can only move to paid version if I can confirm certain features are working as expected.
Kindly let me know how to enable it.

This is a limitation on the trial environment.
