Disabling CWYW?

I am in the midst of figuring out why my Word 2003 crashes everytime I open it after installing Endnotes X2.  In the meantime, I think it might be related to the CWYW function (?) and I want to disable it so that I can at least open my documents in Word while I try to figure out the problem (or uninstall X2 and just go back to Endnotes X1). 

Can someone help me to figure out how to disable CWYW?  Any other thoughts on the Word problem is welcome, too.  Thank you so much!
