try these in order. restart the game in-between steps if unsuccessful... also keep in mind that even when you get things right the bot can bug out from time to time.
1) With the game NOT RUNNING, copy the proper cfg (ie from the low folder if you use low settings) into ur Vin cfg folder
2) use fullscreen mode.
2a) Mouse or Keyboard mode? MUST BE MOUSE MODE
3) the binds in the readme are fine... you can eliminate NUMPAD_DOWNARROW it no longer functions
4) what map are u running?
5) try the other OS setting and report back.
