Sadly biz-engineer, it doesn't even let me even get that far and browse the lens database or select a camera / lens, everything is greyed out.
Anyway, a very prompt reply from Silkypix support overnight , they have confirmed that for some RAW files, correction by lens profiles is not possible as what are considered to be optimum results are already in place.
It appears that this is the case for both the kx and kp raw files, as neither allow me to use the database lens profile function regardless of the lens used. I'm guessing I will just have to live with this limitation - but something for others to be aware of.
As I said it's not really an issue for DA or FA lenses as in camera corrections can be used but for third-party or manual lenses that have a lens profile its a bit annoying. Manual corrections can of course be applied using sliders but I find its hard to optimize.
