This is great information. It proves that I don't need to upgrade... But it won't let me continue.

Please contact our phone support team at 1-888-829-8608 as they will be better able to assist you. They can look at your return with you to see what is happening.

Thank you! I called support and they noted the page is confusing people. It says I need to upgrade (when I really don't).  The options to "Upgrade to Deluxe" or "Remind me later" will continue the application and I can finish without upgrading. It used to say "Continue with free version" or something like that.
