XDP X16 - Design Gallery?

[Rik]

Well, not being an expert on the technicalities of the programme, I've tried everything I can.
But, it still doesn't work.

I've replaced the larger 'eng' file, that's 100Mb, in place of the 10Mb file in XDP11's location.
XDP11 still works fine. I can add page elements etc... in that programme.

However, no matter what I try, things just don't work in DPX16.
What has changed is that I can see all the thumbnails, but, when I try to add anything to a page, nothing happens.

I've added an image to show the steps I've taken, and tried many times.
