I've just installed the upgrade from 5.2.7 to 5.3.8, which DNN reported as a successful installation. However, any pages where the Document Exchange module was displayed now render with a "Critical Error. Object Reference Not Set to an Instance of an Object" error. No modules on the page load. However, I can install the module on a new page from scratch and it runs just fine. Any clues on where to begin looking to see what's going on? DNN logs and windows logs are rather non-informative. 5.2.7 was running just fine...

Specs:
Windows Server 2008 32bit
SQL Server 2005
DNN 6.0.1

Thanks,

Tim

Problem Solved. I discovered that an older version of the DMX Letter Box module was installed on the pages where I was getting the error. Upgrading the letter box module solved the problem.
