Updating credid card detaild

Why is it so difficult?  Keeps directing me to the screen that wants an order number and password! I don't have an order number! I just want to change the details but it seems impossible! can someone help?

I totally agree, it's unreasonably difficult. Don't know why it's not simply bound to Autodesk account... Anyway I found my order number by searching in the email account I had used for purchasing Fusion. Trying searching in your email with a keyword like "Digital River" or an email from "no-reply@autodeskcommunications.com".
