The error that you posted in the screenshot is because of "Third party Programs" that conflict with your game. A solution for this is posted on this thread with a free program that closes all of your third party programs for you.
Take a look at this thread:
And try the program Game Booster. This program closes all of you third party programs for you so there is not anything conflicting with your game. It will also help you get more FPS in-game as well. It is free to download and a large quantity of AVA players already use this program.
Hope that helps.
