Can I purchase a pattern without making an account?

I purchased a pattern, but I did not receive a PDF.

What paper size should I print my PDF on?

I love what I've made with your pattern! Where can I share photos?

When I click on a pattern in "My Projects", nothing shows up on the page.

I entered all my measurements, but clicking "Download PDF" doesn't download a PDF!

I downloaded my PDF, but when opening it in Adobe, an error message pops up that says something like, "An error exists on this page. Acrobat may not display the page correctly."

Where can I find videos to help me take measurements?
