I can't play since update

First : black screen at lauchn : i must do shift+tab to lauchn your ****ing nzivvio logo or nothing happens.

Second : After lauch a new/old game : the mouse is stuck at the middle. (even with changes in Regedit)

Third : your game make my graphics card (Nvidia 970 GTX) scream !!! No others games do that !

Fix it.
