i tunes crash and reset glitch

[PaulMalloc]

I experienced a problem with Itunes on my mac, this problem happened after it crashed or had a hard reset. I restarted the computer and noticed my itunes was reset, no music, playlists, nothing, like I had just installed it. The itunes folder in my libraries is still intact will all the music and other folders, but no matter what files i try to drop back into itunes it just wont go back to the way it was, i tried to use time machine and even tried droping the whole itunes folder back into itunes, it just rebuilt my library but none of the past info (playlists, settings, track count, etc) was restored.

Any body else experience this, know what caused it, or know how to get it back to the way it was?

Thanks,
