Hog PC crashing on entering show

After Installing v1.2, the start menu comes up, I can select a show but when the shows goes to load I get a message saying Hog has crashed. When I look at the Task Manager there are still 4-5 Hog processes still running. I have completely uninstalled and reinstalled as well as trying a fresh download. I have also tried several different shows. v1.1.2.339 was just working over the weekend. Have a load in tomorrow, please Help.
