I recently found my Sansa express and I began putting music back onto it ,but it would not read my kingston 2 GB SD card. It froze for a while and would not have anything on the screen then, I read somewhere that if you hold the volume button plus the select button it would reset it. I did that and it worked then I tried to fix the SD problem by updating the firmware and then it seems to work fine when I plug it in it just says ''Building Database" with it filing up a bar below it. Does anyone know how to fix this problem? And if there is a thread about this I am sorry.
