Can't play video error

[AC Question]

I have a LG G3 and about a week ago I recorded a video on my phone and a few days later I get this can't play video error. Then yesterday my friend sends me videos over kik and they play at first but now none of them play and all I get is a can't play error I'm extremely frustrated with this please help. I tried mx player nothing showed up I tried playing it through third party apps and they would say it can't open what the hell is wrong with the files all of a sudden?? they're saved on my phone not on my SD card.
