Why aren't pics and songs showing up on my Z10?

I have pictures and songs stored on both my Z10 and a media card in it but, all of the sudden, when I open either the music or pictures icon it says that there is no pics or songs. Any suggestions?? Thanks

Was your media card working before? Is this after the upgrade?
I would remove the card, reboot the phone and then put the card back in.

Same to me after install "Call Saver" and "Call Blocker" from app world.

Delete it and all ok.

Check the latest applications you have installed.
