Hi guys, Just a(hopefully) quick problem, I changed my Photoshop preferences yesterday and switched my Scratch disk to a drive I have moved into a free bay in my Leopard based mac pro, when I have come to launch PS CS3 today it refuses to launch, giving me an error message saying " Could not initialise Photoshop because the drive is not available". Is there anyway of booting Photoshop in some kind of 'safe' mode so I can get past this to change the prefs back? Or can I delete the preference files from somewhere? Hope this is an easy one to crack ? Oops, Jumped the gun and posted this as I needed an answer quickly, solved it by deleting my preference file!
