Im trying to add the CC processor we use to the store and create a new payment module. We use USAePay.
They have an API but I can not seem to get it to work with the store. So I tried to recode the Authorize.NET assembly changing it to work with USAePay instead. I then added the dll for this new assemply which I called Nop.Payment.USAePay.
I then added this information as a new payment method using the Admin panel. I then created a Template to use and finally got it all working up to the point where I try to process the payment. When I click NEXT on the checkout screen I get an error Object Reference Not Set....
Is there something special I need to make sure I do to register this new payment method and assembly?
