Hello. I am using CR4E version 12.2.216 and am having similar issues. I have a report that is running a stored procedure. I programmatically change the connection parameters at run time. When running the report, I receive the "Unexpected database connector error" when running setTableLocation. The report runs with no issue in the Crystal UI, but running through CR4E, I receive this error. I read that there was a fix for this (SP2?? - but dated a couple of years ago) but I have downloaded the latest CR4E and still run into this problem. Any help would be appreciated.
