Recently got CK. Version it installed was 104a. 1st day no problems, used autosave many times. Last night auto save would start to load then stop when the green bar was 95% filled, then the screen would go black then a Microsoft program error message would appear. Looking in this forum this post appeared earlier, but one of the replies said that 104a fixed this. I recently installed SP2 which some posts said has caused problems. Looking for ideas and am also puzzled that this has started only after many hours of play. thanks.
