Hello Flyclothing, I do not know if you saw my last post about PayPal advance, where I mention that PayPal people directly told me that they can't get the module to work correctly since all the configurations are hard coded into the module, the only people that can help is Prestashop since they are the makers of the module, good luck trying to get anything out of those fellows, I send a mail a long long time ago I never got a response you are better off looking for other options.
I might suggest look into Brain Tree they give you free service for the first $50000 if you are in the USA, I put my application today as soon as is approved I am making the switch.
