I accidentally entered "C:\" for the plot styles search path in options, and now AutoCAD 2005 crashes a few moments after launching due to it trying to search/index the entire C:\ drive upon load-up.  Is there any way to reset the plot styles search path from outside of AutoCAD?  Like from the DOS command line or a text config file that I can set the original search path on?  Or am I resigned to reinstalling AutoCAD from scratch?  I am running AutoCAD 2005 on Windows XP Professional.  Thanks in advance.
