everytime I try to use the paint fur tool, I get a fatal error message and the program closes. The error message says something to the effects of "fatal error: problem saving temp file in C:Doc&set/localsetting/temp/blahblahblah"

I am a new student at Gnomon School of VFX, so I'm still trying to figure out the settings. If somebody could please help... I am using MAYA 8... Thank you...
