I purchased Elements 10 some time ago. A couple months ago, I had to replace my computer, and I had some difficulty installing Elements onto my new system (Win 7 64 bit). I finally got it installed, and now today when I clicked CTRL+I to edit a photo, I received a display box offering me a choice of either using a "Trial" version of Elements 10 or BUY one. WTF is going on here? I have been using Elements 10 for over a year, and a couple months on my new laptop. I've tried looking the in the HELP or About areas for the serial number to key in again, but I can't locate it. NEVER again will I buy downloaded software from Adobe (or anyone) ... I want the serial number where I can see it. Does anyone have any idea why Elements suddenly thinks I don't have it installed? I've been using it regularly for the last couple months since reloading it without any problems. I have to edit some photos quickly ... HELP!! Where can I locate my serial # to key into the boxes on the display?
