I run this program as a plugin with lightroom or stand alone, I have a new imageprograf pro-300 and when I pull up the ppl the window comes up but will not let me load pictures into software.  I have uninstalled multiple times and reinstalled several times. i run Mac os, and this program was working fine until yesterday getting very aggraviated and about to send printer back to canon.  Canon software is horrible. Has anyone experienced this issue with Print and layout program?  And the website says award winning service, I have been on hold for 2 hours, thats not award winning service.
