problem with endnote x5 alongwith word 2003

Dear all i have a serious problem in using end note x5 with word 2003 the reference comes like this in the text {Andreoli, 2007 #253} not like it should be. I have tried with a new word document and it is working fine if some one has an idea how to solve this issue kindly let me know.

That is not a serious problem.  Cite while you write is turned off.  You want to run “format bibliography” from the endnote tools, and make sure the correct output style is selected.  Also, you can turn CWYW on again from the third tab of the format bibliography dialog.  (enable)
