"Receive file lost connection" when Get HD Files pressed

I just had a 90 minute session and when we were done, I went to Get HD Files and again I got the Receive file lost connection. Is there something special about when you can get the files? It seems like it should work without an issue but the byte count stays at zero and it times out. I was still connected to the performer and we could talk while I tried to get it. Let me know if there is some step I missed in getting the files. Fortunately, he found the files on his computer and can send them to me if I can’t get this working. Other than this Get HD files issue, the session went without a hitch.
