Generating reports failed

Hello,

I tried first the evaluation copy of the modeler edition.
All the features were working. Today I decided to buy the software and I imported the key for the 15-day license.
After installing the key, I can’t create reports in our main project.
After starting the report, nothing happens. I don’t get the window where you can choose the diagrams.

In a new project the report is working.

After that, I tried to create the report with the evaluation license. But it is the same. I can’t create the reports.

Does anybody have an idea?

Thanks,
Sebastian
