Windows Media Player 11 File Sharing Help

Hey guys, I'm having issues with Windows Media Player 11 sharing media. I have Windows Vista Home Premium 32bit. I've actually never had this problem before. For some reason, my media is not being added to the shared files on Media Player. When I add the folders that I want to share, it shows that it found like 7,000 different files, but when you look at the "added" tab, it says 0. I've been using Windows Media Player 11 to share with my Xbox 360 and PS3 for the last two years and never had this problem. I recently did a complete restore on my PC, and it hasn't worked right since. I'm not sure what I'm doing wrong. Any help or suggestions would be appreciated. Thanks.
