I recently upgraded to Windows 10 and all was fine for a day, then the next my computer wouldn't function. To recover I had to lose all my apps but kept my files. When I re-downloaded iTunes it found my music, but the playlists I worked on for three years were gone. I have BackBlaze backup and I re-dl-ed iTunes to get the XML Music file which is supposed to restore playlists by importing, but it didn't work. Do I have to delete all the files that came with my new iTunes dl? Starting from scratch is daunting to say the least, so any help would be appreciated. Cheers!
