My game is broke

[SORRROW]

Hello, I've been playing since open beta 3 and no problem so far, but since yesterday my game is simply weird.
Once in game, all text boxes are empty, there is glitch everywhere, I basically can't play, I tried to reinstall the game but it did not change a thing, bug is still there and I honeslty don't know what to do.
I'd have posted a screenshot but I don't know where they are saved, can't find it in the directories.
