I get the error “Could not initialize photoshop because the preferences file was invalid (it has been deleted)”

Problem solved!!! I held command+option+shift keys pressed while launching photoshop and a box pops up and you choose the option to delete the preferences file

CS5 Mac OS X version 10.9.5

What version of Photoshop and what operating system?

Moved out of the Forum Lounge and over to the Photoshop General Discussion forum.
