I have created and validated my account. When I click on 'Start Learning' from the Systems Architect Essentials page, I am brought to a 'Pega 7' page that says "SSO encryption hash does not match PRPC" and asks for my username and password. I put in my email address (because I never used anything else for the login name) and it says my password is wrong.

Please fix ASAP. I have an employer that requires that I complete this course within a short time frame.
