I upgraded from pse 9 to pse 10 a few months ago. Until yesterday, everything worked okay. Yesterday, as I uploaded some pics to my computer (win 7), the pics were uploaded to pse9, not pse 10. I cannot find any trace of pse 10 on my computer. Where could my pse 10 have gone? How can I get it back? Do I have to reinstall pse10? Please help.
