EndNote tools in Word 2008 disapear every time I close Word

Ever time I close Word 2008 and reopen, the EndNote tools are not showing in the Tools menu.  I have to go to Tools > Templates and Add-ins and recheck the CWYW resources.  Why won’t they stay selected?

IN case anyone else has this problem: We solved this issue using the FAQ http://www.endnote.com/support/faqs/CWYW/faq1.asp#macENX3

Apparently the CWYW files were on the computer, but not in the Word Startup file, so we had to manually enable them each time.  Copying an alias to the Word Startup folder worked.
