How can I install PS Elements 10 when get error message, serial number not valid
I have a new computer (PC Windows) and want to install my PS Elements 10 and Light Room 5.2. When I try to do so I get the error message that my serial number is not valid. I have used the help/support and have done what suggested but nothing seems to work. (The copies were registered.) Please help me solve this so that I can't get my pix edited. Thanks so much for any help you can give me.
