If you require any kind of technical assistance with Musicnotes (involving printing, purchases, billing, etc) — please contact their customer support team. They’re fully staffed and great about helping customers in need.
Likewise, the Musicnotes Help Center has tons of FAQ pages covering just about any question you may have. There’s a good chance you’ll find answers there to any questions I haven’t covered on this page.
I am not a Musicnotes employee, and have zero access to their internal support tools. Similarly, I can’t access any information about customer accounts. Hence, me sharing the links above. Best of luck!
