DXO PL7 hangs


I’ve downloaded the new release of DXO PL7.6, restart my PC, updated my NVIDIA driver and PL7 hangs, when zooming from 25% to 80% displayed.
Then, the ring gear icon run, run and run and I have to shutdoiwn DXO via the Task Manager.

I’ve used some settings to develop some raw pictures and twice time this evening, PL7 hangs.

Thanks for some help.
