I've uninstalled, then re-installed CS4. While I can get at CS4 Illustrator, Bridge and InDesign, the one I need (Photoshop) doesn't open. I get the error message "Could not open a scratch file because of disk error." When I click "OK," the program shuts down.
I'm open for your suggestions.
Try resetting preferences in PS. Start PS and immedately hold down ctrl alt shift keys (Win OS). You will get a reset window if fast enough.
Mac cmd option shift
If this works go into preferences and see what your scratch disk is set to.
Thanks. The fix seems to work.
