Why are my apps not read from the SD card?

[AC Question]

So my phone was low on battery, i left it and overnight it completely drained. In the morning i put it up to recharge. After that i turned it on and some of the games that are on the SD card can't be accessed. I get the message saying the app is not installed. The SD card is in my phone. I tried to unmount then mount again, didn't work. I pulled it out, put it back in nothing works.
What could be the problem?
