[MKEAN]

I first purchased PP for my windows laptop several months ago. Had no problems using PP. One month ago I upgraded to an iMac with Intel Core i5. Loaded PP for mac and have had troubles ever since. I use it in conjunction with Elements 9 and I am able to go in and edit with PP but EVERY time I save and return it completely kicks me out of Elements. Not only did I just spend time working on that image and now have lost it but I have also lost everything in my Elements workspace that I have spent LOTS of time on. Can someone Please help me???? I love PP and really want to figure this out. Thanks in advance!
