Hmm, this screen shot helps. It looks like it loaded the save so that function is fine, but the second it got to the room something caused an error and caused the code in the room to fail to load. When you ran the game before did it run laggy? Is the computer your playing on particular slow like a laptop?
I want to test a few things but I need someone who is getting the bug to be a guinea pig.
