Crystal Reports Exception

Hi,

I'm getting the following exception:

CrystalDecisions.CrystalReports.Engine.LoadSaveReportException: Load report failed.

I'm loading the same report with different data based on user selection from a listbox. This works just fine ordinarily. The user can select an item, view it, close the viewer, load the next, etc.

The exception only occurs after the report has been exported. Doesn't matter what the export format is ... PDF, doc, xls, etc. The only way to regain funtionality is to quit and restart the app.

It can't be that the report is getting locked. I have 4 separate reports, all very similar, but with slight differences. None will load after the export.

Any ideas?

Thanks,
MattMatt,

I am experiencing the same problem. Did you ever resolve your issue?

Eric|||So am I! Did you ever find a solution?

Regards!|||Open the Report and Do verify Database|||And if that dont work then drop the connection and build it again.

Cryptographic Exception

Midway thru a report development I get an error:
Cryptographic Exception: The parameter is incorrect.
I'm told to look in the task list for details, but it is empty. I've
previewd this report a dozen times during the design and now it barks. This
is the first time i've opened it today, yesterday it was fine. I'm
referencing a stored procedure in SQL server and can view the data from the
data tab. Not sure what to do.
Any suggestions appreciated.

RichardDid you ever find out what this means. I just re-opened a report I worked on
last week. THe report renders but I get the message when trying to export the
results to ANY format.
