Don't know why no-one told me to go to TOOLS > FOLDER OPTIONS > VIEW and just click RESET ALL FOLDERS
Cos that appears to have worked
Tho it does I have to now manually re-do ALL the folders on the PC (that I use) to get back to the view settings I had before I reset

Thats gonna take a fucking long time

My music folder alone has 267 folders in it

Not to mention the ones inside each folder
