pa.exe doesnt work

Hello.
Two Seconds after start the game, this happen. I dont know why, yesterday i could play and now i cant.

Post your dxdiag please

Here it is -->

Hmm, I guess you do update your graphics drivers.
Next random guess, maybe you have installed something listed here: http://steamcommunity.com/app/233250/discussions/2/558751813508748383/
?
Or did you change anything else between the last time it worked and now?

No, i didnt change anything. I updated my graphics drivers and reinstall PA.
PD: I dont have these programs that can crash the game.

NOW I CAN PLAY. I forgot restart de computer when installed the drivers.
