Can't Edit Form Fields « Gravity Support Forums

I've seen and read most of the other similar topics for this issue and attempted all suggested ways to fix it, but I'm still not able to edit any new form fields. I purchased the Developer version because I heard so many great things about this plugin. I installed it on one other site I designed with no problems whatsoever, but now am encountering a problem:

I created a new Contact form and can edit the Form ID just fine. But whenever I add fields within that form, I can't edit them specifically (to change field length, required/not required, etc. The Duplicate and Delete work just fine... just not the edit.

I'm running the latest version of Wordpress 3.5.1, and PHP version 5.2.17. I've changed themes, deactivated ALL other plugins except Gravity Forms, and nothing works. I upped my Wordpress memory limit to 64MB and contacted my host company. They told me on no terms will they increase their PHP beyond 32 because of the draw on their servers. So I installed a Memory plugin and according to it, this site only uses 54% of it's memory.

I checked in Firebug and DID see an error in the "prototype.js ver1.7.1" that says "TypeError: element.dispatchEvent is not a function." I found a solution online to add:

<script type="text/javascript">
             jQuery.noConflict()
         </script>

to the head and while that got rid of the error, the forms still won't edit. I'm not a developer/coder so I really have no idea what I'm doing and if it helps.

I'm at a loss... help?
