Paypal Express Checkout not Tracking using the API through WooCommerce

I just spent an hour on the phone with paypal and we are at a loss without some serious coding to integrate Enterprise into the site. Paypal standard is tracking both the trip out and the transaction, and, it posts the sale back IF the customer directs themselves back to the site. The problem is that without the customer being a paypal member, we cannot FORCE the trip back to the site, so we are being forced to use the express checkout.

Now I would think that there is an easy way to fix this issue being that a common setup MUST be wordpress using woo commerce and integrating affiliates enterprise. I have all the settings correct and still cannot track correctly using express. I appreciate in advance your assistance!
