Unable to select slide(s)

Hi there

I was wondering if this has happened before?

I can create a new slideshow, set up parameters, then when trying to add slides I’m taking to my media area, I ctrl click to dd more than one slide, click insert images, I’m taken back to the cyclone backend, however, no slides load.

Any thoughts advice would be great

Many thanks
