endnote and word crashing, unformatted citations

Hi,

I am having a problem with end note x9 and word both crashing at least once a day while my citations are updating. I am using windows.

 Also, my citations are randomly becoming unformatted. I have read many questions and answers in this forum but most are saying turn the instant formatting on. I have turned the instant formatting on and off, restarted word and endnote with no success.

What am I doing wrong?
