Patipada on "[Plugin: WooCommerce Shopping Cart Export] Exported xml feed is empty"

Hi,
I would like to test with the free license. But my export is empty.
What I do:
- create new feed
- csv/xml export
- feed type xml feed
- all categories
- standard
- get feed

Now an url pops up: http://patipada.nl/?feedtype=X&category=0&aggregation=S&RequestCode=CategoryProducts

But this is empty?
When I go to manage feeds I als don't see anything.

Looking forward to a solution.

Thanks,
Gerjan
