Thanks to the help of Yellow I have figured it out my problem with PayPal IPN. I hope this helps others. I installed the IPN module well over a year ago there is a patch release for any one using zencart version 1.3.7and before. This can be down loaded here:

Its easy to tell if you need this patch. If you do not have a field for Payment Data Transfer Identity Token in the paypal ipn module you will need to do this upgrade. The field to enter this is is located at modules>payment, click on paypal ipn then edit. If its not there that is your problem.
You will also have to enable Payment Data Transfer in your PayPal account. When you do this you will receive your token.
Hope this helps & thanks again Yellow!
