when magix say personalised support do they mean you need a current subscription in order to get [free] one to one support I wonder ?

no problems with the effect that I can see with my xdpx15.1

I used to use it a lot, these days not so much, but occasionally black and white profiling [eg the pre-set chrome] is useful - of course if you need profiling you can't use the colour editor...

no idea what the problem might be I'm afraid
