You have me at a disadvantage I don't understand what your telling me. For a year I've worked with version 1.8 with some success now with 1.8.5 I'm having a heap of issues it's spoiling the hobby.
When I go Explorer Windows, Format Explorer, DSLR-Raw, Edit preferences, Raw format preferences, then I have a choice to set up as Pure Raw which opens my images and processes them as GRAY rather than RGB, or do I go De-Bayer RGB click ok. In each of these options you have further options and I'm not sure which need to be ticked for the best result.
I've never had to do all this with version 1.8 but we are where we are, can you help you will need to make it real simple.
