I'm trying to download files from the Adobe Document Cloud > Adobe Scan folder to my desktop Mac. I click "Select All" at the top of the list, then click Download. A dialog box opens, asking me where I want to save the file, which is named "binder.zip" by default. I click Download, and an alert immediately appears saying "Download Failure." If I hover the pointer over the message, a red balloon appears with the unhelpful message "An error occurred while downloading this file."
