If Photoshop seems to be fighting you at every turn, and you keep getting told that it "could not complete your request because of a program error," here's how to fix some common problems to help ...

Photoshop checks for this file each time you open the program, and if it doesn't find one, it will create a new file in the system folder.
Possible fix for "program error" messages We previously reported on repeated error messages that state "Could not complete your request because of a program error," in the Photoshop CS3 beta.
PSD support is built right into this open-source solution, meaning that you don't need to worry about third-party plugins. GIMP can process the individual layers of a PSD file.
