It seems iTunes updated itself to version 11.1.3.8 without asking (I was runing a 10.x version and didn't want to upgrade to 11.x because of other issues) and it totally screwed the pooch. I also tried going back to the 'C:\Users\(Username)\Music\iTunes\Previous iTunes Libraries' folder but it's empty. I've copied the files back to the itunes folder but I can't get them to display in iTunes.
Right click > Show in Windows Explorer works fine here.
