My program has been running successfully for many years.

All of a sudden we are seeing the C5 error on this line:
This.crReport.ReadRecords()

The first time the report is run, it is OK. The next time, it gives the C5 error.

I use Crystal reports 9.

If I exit my program and start again, the report runs fine again the first time. The next report gives the C5 error.

Any suggestions on what to try?
