Import Export Tools to export cck custom content type

Hi,
i'm trying to develop a module which needs several custom content types.
I would like to save some time by creating the installation code for the custom content types
and thought i could use the export functionality of the import - export tool for cck content types.

After installing cck and the import - export module I got the Tab to export with the list of
content types and view. But after I select a content type and click export
nothing happens. The firefox page is blank - no error message. I've tried different content types, page ...
but with no success.
I ve seen the module is not actively maintained but this would save me a lot of time instead
to create all the code manually to create a node manually.

I m using drupal 6.26 .
How can I get this working. Any ideas.
Is ther another way - module to export cck content types?

Thanks,
Bernhard
