Program will not open. gives "unexpected end-of file" followed by "preference file was invalid (it has been deleted)" have reinstalled from disc, but still get the same error.
any help wiil be appreiciated
Preference files are usually not touched during uninstall or reinstall. You would have to delete it yourself.
If you need a quick and dirty way to restore your preferences, here's a way you can do it using a keyboard shortcut on launch:
Windows - double-click the PS icon to start Photoshop
Immediately Hold down CTRL-SHIFT-ALT
You will see a delete preferences dialog. Click “yes".
Macintosh - Hold down CMD-SHIFT-OPTION instead.
Thank you for getting me back in. Worked a treat. I was beginning to panic.
