Adobe Photoshop CS3 Extend Error

I had to re install Adobe Photoshop CS3 Extend but now every time I try to start it, it errors out withe the following:

"Could not load the user measurement data point presets file because the file name was not valid."

and "Could not load the user measurement scale presets file because the file name was not valid."

Any assistance would be appreciated. Thanks!

reset the preferences per the faq.

(no reinstalling doesn't reset the preferences...) :)
