We just upgraded to Q1 2011. Most of our reports are running just fine, we switched out the old reporting dlls with the new ones. This is a winforms project. When we open a form and click the report button, the report shows up just fine. When we click the print button the report viewer toolbar, an error is thrown saying NullReferenceException was unhandled Object reference not set to an instance of an object. But when we're debugging, there is no source available, just the error. We can't figure out why it is just these 2 reports that aren't working when all the other ones are. Any ideas?

Hi Amanda,
The error is too generic to be able to provide an answer what is wrong and we can only guess without more information. Are you able to export the reports to any of the formats or you get the same error? First check the Output window in Visual Studio for any errors, and also enable CLR exceptions from VS menu -> Debug -> Exceptions.
If none of them yield any problem, please provide us with the problematic reports (runnable versions) which exhibit the problem and we would advise you accordingly.
