Paradox is not such a friendly forum as it used to be. It now insists upon tracking you and monitoring your activity. I am no fan of Steam, but it is slightly better than Paradox with regard to being gamer friendly. My suggestion, just search and view the AGEOD forum for Pride of Nations support and discussion.
I recently abandoned my Paradox PON game and the result was so worth doing. I now have a wonderful functional game with no more crashing issues.
