I don't understand the need to upgrade to plus membership. Other than the xtra features, does it actualy give me more space within the software on my computer or is it simply more backup space? My new upgraded Photoshop Elements 10 doesn't seem to be working. Seems locked. There is a message on my screen that I have used all of my storage space of 2.0 gb. Is this why I need to upgrade? I don't understand if the "storage" is within the software on my compter or online backup storage. I don't want to spend $50.00 per year just for back up. Thanks.
