no power, card erased.

My bb would not play the latin sets. when i tried to fix the problem i wound up erasing the data on the sd card, when i tried to fix that i got updating card message and after about twenty minutes of the same message i pulled the plug to reboot and now i can not power up the bb.

Try steps 5-15:

Are you using the Latin drumset with the Latin genre? That is required to have it play, as the Latin genreā€™s mapping is unique.
