I am attempting to scan a lot of old family photos to Live Photo Gallery. I am using Windows 7, and have had no problems till yesterday, when suddenly the photo I scanned and am trying to edit won't show up in the Live Photo Gallery listing of photos.  Is there a limit to the number of pics (or space used for them) in this program?  I have searched to find an answer but get nowhere.  Here's what I was doing:  A.) I scan the pic, B.) tag it, C.) import it. D.) It goes to my LIbrary in the pictures folder. E.) I have been clicking on it, F.) taking the pic to Live Photo Gallery to edit (mainly cropping) and G.)  saving to Live Photo Gallery.  After approx 65 pics yesterday, suddenly the photo cannot be located at the 'go to Live Photo Gallery' stage (F).  It still shows in my Libraries /Pictures folder, but I cannot find it in Live Photo Gallery to edit.  Yesterday I thought maybe it was a glitch or too many for the day, so I stopped and tried again today.  Got to the same spot and it stopped again.....I have loaded up to 600 photos in a day in the past, for sure more than 65 pics.  Do I need to switch to some other program to complete this project????  Can someone please help me figure this out????  thanks
