I bought Adobe Elements 12; I cannot use panorama photomerge, I have followed the directions to go to Full Edit  mode in edit workspace> choose File> New> Photomerge. However the Photomerge does not work, it does not respond.

The only thing I can come up with is that I found a blog that said that in the Trial version Photomerge does not work, however I do Not have the Trial version, I did at one time but I purchase Adobe Elements. Thank you.
