Windows 7: Windows Media Player 12 - library is empty every boot

As the title states, my library is always empty upon booting and I have to wait for it to update and find my music. I've browsed other threads here regarding this, and have yet to find an answer.

All of my music is in the default "My Music" location. I haven't changed anything. The weird thing is, EVERY time I booted it, it used to have duplicates of every song. Now, it boots with absolutely nothing.

Edit: Upon my most recent boot, I took a snapshot, as I have nothing but duplicates of EVERY song. This is the one time as of late that it kept everything, except, duplicated everything.
