I was trying to set up the Standard IPN first, but after discovering the Paypal problem with the IPN i switched to Express Checkout.

And im afraid that maybe the Reward Points Module is causing this SQL-error when clicking the button without being logged in.

So i just want to make sure, is this mod working when using Paypal Express Checkout?
