Hi Martin,

I am getting this error:

Unhandled exception has occurred in your application. If you click continue, the application will ignore this error and attempt to continue.

If you click quit, the application will close immediately.

Cannot call StartAt when content generation is in progress.

See the end of this message for details on invoking

just-in-time (JIT) debugging instead of this dialog box.
