Hi Vanessa,
Ludek asked me to try your report in my SDK app and it too is crashing it. I have an open case with DEV right now on another report that also crashes crw32.exe and they found the cause. I tried their fix with your report and it still crashes it so I sent it off to DEV to see if they can find the problem and possibly fix it so the report can be opened again and hopefully you'll be able to fix it.
Any chance you have a back up somewhere?
