If one of your activities would throw an exception, the workflow state information would be deleted from the database. Run your workflow debugger with "break when exception is throw" configured in Debug - Exceptions - Common Language Runtime Exceptions

My activities should not throw any exceptions. I think that I am missing something - after first activity workflow continues to the second activity ... Where is the "break when exception is throw" option?

See Debug -> Exceptions, check the box after "Common Language Runtime Exceptions"During what step in the flow do you get the error? Right away when you call PassA to signal webServiceInputActivity1?

I have absolutely no idea why the next day the same code worked ok. Anyways - thanks for your time.
