LG G4 Messages Problem

On the default messaging app for my LG G4, when I send or receive messages they don't show up on the app. When I get messages, the are aclnowledged and the phone knows they are there and it shows up in the notifications, but not when I go to reply.

I was doing an exploit on a game where you put the time ahead to speed things up by X amount of time. I received a text message from one of my friends when it was on the year 2036, and now I can't read any messages I receive and send.

Thanks for the reply. I figured it out already.
