Hmm, that's not much information you give us to help you...
Which Chapter? What's the exact problem? Is there any error? (If there's any, can you upload your traceback.txt?) What was the last version you played? It might also help if you upload your not working save file...
I'm sorry, but an uncaught exception occurred.
