cygwin error

[Ray Percival]

I have installed cygwin on my pc running windows 2000. Over the weekend I was able to bring up multiple windows using it, however this morning I am unable to even bring up one window. In order to troubleshoot it I modified startxwin.bat to initiate XWin with the following command:
     run XWin -multiwindow 
now I get a fatal error message window directing me to look into the /tmp/XWin.log file for information. Here is what I found in C:\cygwin\tmp\XWin.log:

Welcome to the XWin X Server
Vendor: The Cygwin/X Project
Release: 6.7.0.0-12

Contact: cygwin-xfree@cygwin.com

XWin was started with the following command line:

/usr/X11R6/bin/XWin -multiwindow 

ddxProcessArgument - Initializing default screens
winInitializeDefaultScreens - w 1024 h 768
winInitializeDefaultScreens - Returning

winValidateArgs - g_iNumScreens: 1 iMaxConsecutiveScreen: 1
winCheckDisplayNumber - Cygwin/X is already running on display 0

Fatal server error:
InitOutput - Duplicate invocation on display number: 0.  Exiting.
