After upgrading from Nintex 2010 to 2013, I was not able to open the Task form using Nintex Forms, but it popped up and then did not open the Nintex Forms designer. I had tried fixing it by Reactivating the Nintex forms for Workflow feature as explained in the below article
Does anybody have a solution for this ?

I figured out the reason behind whyI could not use the forms designer for a task form. I used IE8 which has issues with the Nintex forms designer . so I upgraded my browser to IE9 and it worked. Seems like the form designer works better with IE9 and IE10.
