"1-Why do my pix come out blurry when opened from Organizer? 2-What are the blue checks and the red icon?"
We can't see what you are seeing, so the best solution would be to attach a screenshot to a reply in this forum (not as a new discussion).
However, a blurry pix in the organizer generally means that you are seeing a thumbnail (360 x 240 pixels) and not the original file. When enlarged to your display size, it's necessarily blurry. The reason would be that the file is no longer in the location on your drive as it was when registered in the catalog.
A screenshot would explain the blue and red icons you are seeing.
