did you check your ELO ? did you actually lose points ?
I checked, and it seems it was only the display of points change which was inverted ; example, it was showing -20 for you, and +20 for your opponent, instead of +20 for you, and -20 for your opponent, but the calculation was ok, and you were still getting your points...
About give up, if you do it when the chat is opened, it won't be counted as a give up, just like a normal end of game (so you may win or lose points, depending of the current score)....
You can download the latest version again, I corrected the display of the points change.
