Cannot upload document to send for signing

I have sent documents out hundred of times.  Now when I try to send a document, I input the email address of the recipient.  Go down to continue, press it.  All of a sudden the email and document is gone and all I can do is upload another document and reinput an email address.  I have made new copies of said document to send, always the same issue where I cannot get adobe to load the document and send.

Any ideas?
