Long story short - I created an app in VS 2012. Installed SAP CR and was in a healthy bliss. Unfortunately, environmental changes forced me to change to VS 2010. In doing so, all of my reports will not work. I can open the report in VS 2010. I can verify the database. However anything else I try, the report just crashes. When I run the application and it calls the Crystal Report, it just hangs. One of the things I noticed is that I can see the server, the username and password which I pass to it, however I do not see the database variable passed correctly.
None the less, everything crashes when I try to mess with the crystal reports. Any help would be appreciated.
