I just upgraded from MS VS.Net 2002 and 1.0 framework to MS VS.Net 2003 and 1.1 framework. After, I loaded and upgraded a .Net Windows application that incorporates some Crystal reports from 1.0 framework to 1.1 framework. I re-referenced all my Crystal Report files being used in the application. When I try to preview a report in the Crystal Report Viewer control I get an error stating Invalid Report Source. I have been to the Crystal Decisions Web site and found a Hot Fix, but it did not solve this issue. Any help is appreciated.
