I get an error when trying to open Photoshop CS6. "Could not open a scratch file because of a disk error." "Could not initialize Photoshop because the preferences file was invalid (it has been deleted). If I right click on the Photoshop CS6 Shortcut I can open as an"administrator" but when this happens I can't seem to drag an image from a Windows 7 explorer window. I'm not sure if these two problems are related or not but my production has now come to a screeching halt.
