Files appear in playlist with 0:00 time no playback

[Tabryne]

Anyone else have this problem? I have about 1/5 of my music files show up in the playlist with a playtime listed as 0:00. When I try to play them (using the classic skin) the square beside where the > Play triangle is goes to red and doesn't play, but the same files play fine if I use windows media player or listen to them on my phone.

Anyone have any idea what could cause this or know of a fix?

Thanks for anyone that can help with this!
