Video playing problems

[Zomboid]

Whenever I try to watch a video, the sound and everything is just fine, but the picture itself is really fucked up. For example, on vlc, any video is cut into like 5 seperate pieces, all showing the same thing, in black and white, in the top left corner, and if I maximize it it's just blank. In windows media player, it plays the video upside down.

Wtf?

your computer clock is accidentally set a day ahead and thinks it is April Fools Day.

Try setting your date back to the correct day.
