Albums and Artist doesnt show in the library. Help!

[Povasmcfail]

I love Bs Player and i have probably used it for over a year now, but i got a problem right now.
I recently formatted my harddrive. So i reinstalled Bs player (after i installed windows xp sp3 on my computer.) and started adding my old mp3 files to the library again.(i had them on my portable harddrive.)
But now the artists and albums doesent show for my songs anymore.
I've looked around on the internet, but i didnt found a solution for my problem. In fact i didnt even found any one that had, or have, my problem.
So please help me, your my last hope.
Or else i have to find another mediaplayer, and i really dont want that.
(Im using Bsplayer free)
