I have a Crystal reports recently upgraded to Visual studio 2010. All the reports works fine except a few of them having issue when I click on the 'Group tree' very first time. I am getting report load failure. I checked the TEMP folder for the .rpt file after loading the report but there is no file. The same report worked fine on 2008. If I go back and reload the report, the report works fine. What could be the issue? Please let me know. I appreciate any suggestions. Thanks.
