On October 17th, I responded to the Microsoft Notification to upgrade a couple of programs, one of which was Photo Gallery (I think).  Anyways ever since then, whenever I try to open Photo Gallery it displays for a few moments, then displays a message that there is a "Compatibility Issue" and then shuts down the Program.  I tried deleting some old MOV movie files that didn't seem to be displaying but the Photo Gallery Program still will not run.  I tried running the Compatibility Troubleshooting steps recommended by the Microsoft Solutions message but still nothing works.  Can somebody help me?   Steve H.
