Harmonium

I am taking the beginner harmonium class and started yesterday; I am having trouble logging in so that I can access the forum and homework; when I try to create a password it says I already have one, which I do not, to my knowledge. I am anxious to get started and have sent an email to the main website. Any other ideas? No one ever gave me a password that I know of, other than the main one to access the main page. Thank you for any help you may offer.
