Try to create a new Catalog Type - DataGroup Catalog Editor crash

We work with ProjectWise SS4 with a Managed Workspace for AECOsim SS6.

It's the first time I want to create new Catalog Types.

At first I have created a new XML file in the Company Dataset.

This worked well.

But now when I try to create a new Catalog Type the DataGroup Catalog Editor always crashes.

  

Does anybody else have this issue?

Regards
