Why is my screen stuck on "Preparing Document"?

I received an email request to esign a document.  I selected the option from the email to "click here to review and sign" the document, but I get stuck on the screen that says "Preparing Document".  In the background (which is grayed out) it say "Thumbnail Not yet Available" but portions of the document are there.  The document never fully generates allowing me to sign.  I have tried signing in to my account and selecting manage documents, but the document won't load under that scenario either.
