Hi,
Sorry, I misunderstood what you said early. I had thought that your photos were on the external drive.
Part 1
Do you still have your version 7 catalog on your system?
If you load the organizer, go to the File menu and select Manage Catalogs. Click on the Convert button - does it show your version 7 catalog?
Part 2
If you select an image with the question mark and look at the information panel, does that say the image is on the C: drive?
