Okay, Development says that for specific sellers upon request, we can disable the part of our code that requires Layout C, so you can set up Layout A/B in your PayPal Manager and see if/how it works for you. To confirm your identity and attend to this request, we would need you to email Support with your E-junkie account password, or your Subscription ID (from your Seller Admin > Account Summary screen), or your original activation code (from the original "Account information" email we sent you at registration):

Bear in mind this would be considered an unsupported hack for use entirely at your own risk, as we have not tested this at all nor researched any settings or other parameters that may need to differ from the standard setup for Layout C, so we can offer no guarantees. Once we disable the Layout C requirement for your seller account at our end, you would be expected to configure any needed settings in your PayPal Manager and test it on your own to make sure it actually works.
