Can't Play Audio , Help Please

[Bleedblue12345]

Well, a really weird problem just happened. I was playing a game (WoW), then when i went back into windows to use windows media player, it gives me and error. I tried reallpayer and foobar, and same thing happens. I have tried restarting, and I have tried resetting my x-fi to default. Any Suggestions?

Unable to open item for playback (IWMSyncReader::OpenStream failed (C00D0BBD)):
"C:\Documents and Settings\Owner\My Documents\My Music\All American Rejects\01 Dirty Little Secret.wma"

cd's, online radio, and youtube play fine....

Thanks
