Nintex Forms: Cannot open designer "An error occurred during an ajax call."

Recently I have installed the Nintex Workflow Forms and configured it.
I have activated the web application feature and site collection features and all, however when I try to customize a list forms using Nintex designer I started getting error message that says

 "An error occurred during an ajax call."

When I did IISReset, it seemed to have fixed it.

hope this small piece of information will save your time!
