Dualshock 4 is not recognized all of sudden

[agger]

I played The Legend of Heroes : cold steel It had been perfectly worked til yesterday. It suddenly doesn't recognize my controller. I tried to change the setting but nothing worked. I tried playing the other games if there's something wrong with my controller but it worked on every other game or platform. Even keyboard doesn't work at all. I downloaded a different version to check but it didn't work as well..
