I have Deep Sky Stacker on my desk top and up until now it has worked a charm no issues at all.

Now it goes thru the stacking motions and then displays a blank grey screen and small control box (rgb lum and saturation) are both grey ...no completed stacked image.
The sliders in the box dont respond.
I have uninstalled dss and downloaded it again.
We (my daughter is helping) can not work out where the problem may lay.
Any ideas?
