Photoshop CS doing self-reset of brushes

I'm using Photoshop CS on Windows XP.

Everyonce in awhile, usually after I have to force-close PS via ctrl+alt+del and end task, Photoshop wipes out all my Brush presets. I save all my brushes as a giant abr file in a different folder on my computer so I can get them back easily. However having it wipe out all the saved brushes in my Brushes folder and on my Brush view is incredibly annoying. This will occassionally happen on it's own, so I don't think it's a problem with using a forced close. It always wipes out any color presets I have, and will occassionally wipe out my gradients, but not always.

Any ideas on how to stop this?
