How do I get rid of an error that pops up after I was prompted to update my Asus tablet?

AC Question

Lots of people in the forum had experienced this but the link provided to solve the problem is no longer active. The gallery and camera won't work and the error continually flashes up. Something like android.media.process keeps popping up. I haven't had the tablet very long and so this is quite disappointing. I want it sorted asap.
