Crystal reports keeps crashing on me when I try to add a calculated field to the report. When I created the calculated field, I did not get any error messages, i still don't...however, every time i try to add the calculated field to the report I get the error that says...
"The instruction at 0x0089ae13 referenced memory at 0x00000020. The memory could not be read. Click on OK to terminate the program . Click on CANCEL to debug the program"

Does anyone have any idea as to why this is happening? I copied the report and DB files from another machine, onto another one that has crystal reports installed. I can open the view the data in the DB, and am able to connect to the DB. Everything seems to be working, until I try to add the field to the report.
Any help would be greatly appreciated.

Thanks,
