I have the same problem. Everything seems to work, discount codes show up fine in admin, always fails during the ajax check, and is not applied in the final checkout. I'm not sure where in the process it's failing, or how to find out.

I installed the most recent version and am trying to use the "Trustee Merchant Host" option. But after entering credit card info on checkout_payment.php, I keep getting redirected to the login page! I have been scouring the code and I can't figure out why this is happening.
