Thanks for the very rapid response. Checked the volume on the player and it's fine. Now I'm having a Senior Moment (a la Rick Perry...). I forgot how to download video lesson files from my favorite instructors. I click on the download button (hoping to get a new, revised .mp4 file in lieu of the old .flv format) and the computer doesn't prompt where to download it. It goes to the screen and I can play the file from there, but I want to save it to a folder to be played while not online. Chrome has been installed on my machine since my last lesson download. Any suggestions?
