In Elements 10 I am finding that my thumbnails have become gray squares with an hourglass instead of actual photos. No one, repeat, no one at Adobe has been able to correct this issue. I am being sent from one department to the next with no success. In addition, I am waiting long amounts of time with no one answering the phone. Also, I cannot even get an answer on an upgrade to Elements 12 to solve this problem. What is going on?
