When downloading pictures, process freezes up - already restarted a few times but freezes up every time on different photos - help!!!

I figured a work-around - when starting the process of downloading/syncing and the Wizard comes up, manually choose (check mark) the pictures that have not already downloaded. I did it by groups of about 200 and it worked. This time.

Thank you ClearNexus - will try this next time!! I did not see your answer in time to try it this afternoon but have a strong feeling I will be utilizing this info sooner than later!
