Well, it was sad to not give you all points, but at least you scored partly in this stage.

And as for the error : After taking a look at the logs it was something different than the last time. If it now crashes I have to kill it with the task manager and the last line in the log is this one :

<LogEvent><Type>Warning</Type><TimeIndex>01:20:25</TimeIndex><Location>GameState.Render</Location><LineNumber>0</LineNumber><Message>Error</Message></LogEvent>
Maybe this will help you locating the problem.
