Good news! My iPod is functioning. I too had to go back to 7.4.3. in order for it work. I then had to de-select all the compatibility settings (that was a wizard of the manufacturers on my stupid PC cause it wasn’t obvious). Thats what finally worked. Unfortunately, I caved and called the Geek Squad; they couldn’t resolve it but at least my machine runs better.
