Some troubles in game

Hello! I'm find very unpleasant bug, when playing tutorial. In the first mission, at the end, i decided to change graphic quality from "very low" to "medium". After reboot i've seen following:

I'm tried to click the only available button, but in the top part of screen appeared this message:
CDogsLobbyManager: <ResponseValidatePostMatch> Error: UnhandleError -> 'NoneType' object has no attribute '_getitem_'

After several minutes of waiting, i am finally could select one of tutorial missions, but here I met with another problem:

Or

The problem in this window. I tried to delete DogsOfWar file directory from C:\Users\...\Documents, change graphic quality or interface language, but there was no difference.
I'am use NVIDIA video card and Win 8.1 OS
P.S. Sorry, please, for my english.

So?..

I am having the exact same issue. It is quite annoying. I have tried restarting the game, re-installing the game, but nothing.
