Go to Settings > Apps > All > Google Play Store and select both Clear data and Clear cache and finally Uninstall updates. Restart your device, open Google Play Store and try to ttrockstars download the app again.

I have the same issue with my Xperia Z4 tablet. If I move an app from sd card back to the internal memory, it can be updated ok. If I eject sd card, restard, re-incert sd card then first 1 or 2 apps sitting in sd card would update and the rest will fail. I've had this issue for some weeks now and I got about 40-50 apps waiting to update. I try to keep as many apps as I can on SD and I don't have enough spare internal memory to move them all from SD at once and going one by one is a PITA. This is seriously frustrating!
