A question that might help you narrow down the possible causes:
Do you get this crash with any filemaker file when you attempt to generate a design report or just one file?
If only one file produces the crash, the file is probably damaged. Recover the file and see if the recovered file crashes while creating the report. If it does not, discard your damaged file and replace it with a back up if at all possible.
If you get the crash with all filemaker files, you may have a problem with your installation of FMP 9 advanced. You may need to trash a preferences file or re-install the software.
Thank you for your answer.
I use many files in an integrated packages. One of the files uses a plugin that refuses to report.
Removing this file from the report everything is OK .
I'll find out why this plugin doesn't report properly doing some tests later.
