Library Unresponsive in Windows Media Player

[baseballbert]

My music isn't showing up, and the folders are "unresponsive." I've gone into the control panel and clicked on "Indexing Options," but when I do that, it doesn't show a list of places like it does here:
Index Locations - Add or Remove - Windows 7 Forums

How do I turn the indexing on in the folders so they will see the music? Thanks!
