Seems Phase One's Media Pro doesn't play well with Windows XP operating system. I haven't been able to import any images without the software crashing and closing itself. Phase One support center finally came up with an answer (Note: This is not the final answer though).....
Dear Michael,
we are now investigating this issue, it seems to be specifically related to the Phase One rendering engine and Windows XP OS. Please go to Media Pro Preferences and in Media Rendering/Raw select other rendering engine than Phase One.
This should solve the crashing issue for now until we find a way how to address in upcoming releases.
Thank you very much for your understanding and for reporting this issue to us.
With kind regards,
Phase One Technical Support
