After submitting an order and providing the credit card information, the page reloads with the following error.

A critical error has occurred.
Object reference not set to an instance of an object.

When I check the log viewer, I get the following information. It seems to suggest that the problem is related to SMTP but I've set up and successfully tested the SMTP settings in both DNN and CataLook. It also seems to suggest to SSL is not enabled. But, I have SSL_Module purchased and successfully installed. Any ideas? Thanks!

Where do you go to discover what versions of CataLook match with which versions of DNN? I've done a search on your site and cannot locate that information.

Thanks, John

Perhaps this is the problem then. I bought your software a couple of years ago when your site was running on DNN3. When you converted over to DNN4, my login was wiped out. Since then, I've never been able to do any downloads on your site. Instead, I have to rely on you to email me the updates. So, I don't have the ability to tell which versions match up.

Thanks, John Tisdale
