After upgrading to Crystal 2008 Runtime SP5 (184.108.40.2060) some reports began failing to render. We found that all the reports that failed to render were being passes multiple active data tables as main table which were being joined within the RPT file. Downgrading back to SP2 (220.127.116.110) got them to work properly again. Has anyone else reported this issue. I have an example RPT file which renders with SP2 but not SP5.
