Mix Vibes won't read my mp3 files

[santacruzjt]

I purchased mix vibes on my old tablet. I upgraded to a new tablet and logged in with the same google account, it downloaded and I think registered, but when I go to select an mp3 file from the sd card, it says no audio files found, even though I can play them in other programs on my tablet like vlc player. Please help.

Cross uses the mediabase. Files should be known in there.

Might you have started before the files were added there.
