Hello AleRauseo,
Welcome to the
PhotoDirector forum
You didn't mention which version of PhD you're using, or what happens when you try to import the CR3 files from your R10.
Here, in PhD13, the CR3s import but display is appalling... so I don't suppose it matters which version you're using
I'm glad you've reported the issue to Tech Support. I'll do the same through my channels.
