corrupt file warning in Wmedia player.

My windows media player is having a problem on my i910 with winmo6.5 on it, it worked fine till yesterday.

When I start playing a random song from the desktop it works fine and will continue to play threw my library but when I open media player and try to look at my music once I get to Library-->My music-->All Music the only folder there is called "WMPInfo" and when I click that sometimes is does nothing and other times I get an error message, something about something being corrupt.
