I have been using Photoshop Elements 10 for over a year. It was working fine, then a couple hours after the last time I used it, I was unable to launch. The message said "Could not open a scratch file because you do not have the necessary access privileges." When I closed that message, another message appeared "Could not initialize Photshop Elements because you do not have the necessary access privileges."
I have deleted anything pertaining to PSE in the Preferences folder and the Saved Application States folder. Still got the same messages.
I would truly appreciate any help.
