Del - You don't really give enough data. Lots of things *could* be the issue.

1. Desktop is what you signed up for at Intuit right?
2. You got a production (not testing) setup at Intuit right?

Also, you ask about ssl cert. You DO have correct and signed ssl for your domain right? If the cert for your domain in the shop does not match - there will be verification errors. I'm suspecting SSL issue for you...
