Can't Check Out Free Of Charge Orders

Hi

If I try to check out using gift certificates or my points balance to pay for the entire value of an order I get the following error and cannot place the order:

Notice Payment method not found. It could've been disabled, or a technical problem occurred. Please choose a payment method and try again.

Any idea what could be causing this and how to solve the issue?

Cheers

If you use 4.3.3., this is a bug. They are working on it now. Please contact CS-Cart support for the solution
