Windows Media Player "Unknown" file. Can't play or del

[xVehemencityx]

Hi. For quite a while now, I've had a file in WMP that I can't get to play or delete. I can't find it in my music library either, and I can't right click > open file location.

All of the sub-categories are unknown as well.

There it is. Sorry about the hugeness. I don't know how to make it a thumbnail.

Might I also note that I use WMP to sync my music with my phone, and that not-song is a problem with my phone too, so if I can't fix it, I'm going to have to switch to something else, which I don't want to do. I like the simplicity of WMP

Also, something else I just noticed: it won't update my library anymore. I cleared my whole library to try to get rid of it, and it didn't go away so I went to put my whole library back in, and it added 90 songs and then stopped. Only 2000 more to go. -.- Except it isn't adding them anymore. It just stopped.
