Cloudmin Paid AMI

Hi. I'm trying to use Cloudmin on amazon EC2 server, but regardless of region/server type combination I use, I get the following message, when trying to create instance:

Client.AuthFailure: Unable to launch image ami-972aecfe as the product code ACD42B6F is not supported for the specified region, instance type and operating system combination. Please contact the vendor for more information.

Is there another method of starting the instance?

I'm using the following guide: http://www.virtualmin.com/documentation/cloudmin/aws/cloudmin_paid_ami
