I contacted the developer about this numerous times and had a good conversation through emails. Providing them access to the administration panel to the website to ensure i was not doing anything wrong and giving them a shot to fix it like they offered.
It seems once they realized that the script would not run on my website due to the Full Ajax plugin, and abandoned the issue. Without receiving any replies to my latest emails and no reimbursement like their policy said should be applicable in this situation, I decided to post here to warn any other Full Ajax users of the issue and so forth.
Again, great extension, but unfortunately poor service in my experience.
