Hello! I have used dropbox in the past to transfer audio files from my phone, to Dropbox and then download to by computer. Now when I add a file to dropbox and try to download it to my computer I get an error message that says "There was an error downloading your file". I have not been able to download from Dropbox since August regardless of the size of the file. I use the desktop version so do not have an app to update. Any suggestions?
