Process Monitor wasn't showing me anything useful. I finally managed to get it to work, but it was accidental and only able to be done in debug mode. The only way it works is if I put a break in before it calls the line to set the ReportSource, and inspect the this->reportDocument1 variable while the program is paused. Once I've inspected the variable, I can click Continue, and there's no error.
The only thing I can guess that is going on is that the program can't read the variable so it dies, but the symbols to read it are loaded to inspect it, which then lets the program read the variable. Following that thought, I checked the version of the CrystalDecision references, and found that they were still pointing to 13.0.2, so I removed and re-added the reference files. Instead of them coming in as 13.0.10, they add back in as 13.0.2, even though the files themselves show their version as 13.0.10. Would you have any idea why the references aren't reading the correct version?
