Well, I have since gotten an upgraded computer and due to working from home, I am using my own with no problems, so....I guess it's fixed! Thank you for your help.
Hmm. When I locks up, I can restart and reload the game, somehow I don't think that is how it is supposed to work, but it is a fix.
It seems to lock up at strange times. Playing on a Dell PC. Just curious is this an ongoing problem?
