Help All of a sudden, the phone will not see my music files


My stock music player, my stock alarm can't see my music files.
The music player claims there are no music files, and when assigning an alarm ringtone, my mp3s are not on the list, even if I try to assign a ringtone to some of my contacts, all I can see are the stock tones.
This, of course, worked just fine up until last night. I installed the Akimbov audiobook reader last night, is it possible that the app is the culprit? I since removed the app, but nothing got back to normal.
Any ideas on this?

PS: the files are there, ASTRO file manager sees and can open everything.
