I can't import music into iTunes 11?

Last night, I ripped a few CDs into iTunes. It worked just fine. I was able to view the albums in the library, edit their information, and import them to my iPhone.

Now, today, I'm attempting the same ritual, but the albums I copy into my computer are nowhere to be found in the iTunes library. I searched the directory on my computer, and they reside in the iTunes music folder, but still do not show up on iTunes.

I can play the music and everything, but even when I attempt to import the folder manually, it doesn't work. Any help?

Check for viruses or threats.

So the files are there its just itunes not seeing them. I can just say reinstall but there's also a lot of better free apps songbird for one that are better you see itunes was written for the mac osx so its not stable on a windows platform and uses a lot of cpu overhead.
