After Update i can't play (CODE: AP401)

After the update i can’t play the game and i get this error (CODE: AP401)

Before this i run the game in 1080p, low setting and i get 45fps to 60fps, the ave. 55fps, the day was released the update i played in the morning and everything was fine (i do not think i had the update), but now i can’t play.

This is my spec:

CPU - AMD FX-6300 4.2GHz
RAM - 8.00GB 1600mhz DDR3
GPU - NVIDIA GeForce GTX 750 OC

Someone else has the same problem, and know how to fix it?
