Hmm. I'm wondering if the blank slate thing is where we should be looking - maybe it's if you install (like me) over existing Rapture / DimPro installations, and it kind of has to deal with all that as well as its own versions of those libraries - there seems to be some overlap.
So I'm thinking I may have to (when I feel like spending an hour on this) uninstall all 3, carefully saving any user presets I may need in future, then install Rapture Pro *first*. Then I would likely install Rapture again, since I have used it in so many projects and I'm not sure how they will react to trying to use RapPro instead - though it might be interesting to find out, maybe it's a clean replacement and can handle that? Seems unlikely, but a person can hope...
DimPro I think I will leave uninstalled, as I have basically never used it in a project. Assuming this is the problem and RapPro loads fast, it would wholly replace DimPro for me. Rapture too but only if projects can magically load it.
I seem to recall Galbanum Piscis being a right pain to get working on Win7 and later (I'm on 8.1 here), requiring registry hacks, but now it seems to show up in my CCC so maybe that will be resolved?
