MS Word freezes sometimes when I try to insert citation(s) or close MS word to exit

Hello,

Not sure where to post this but can anyone help?

My MS Word freezes/hangs a while whenever I try to insert citation (s) sometimes or whenever I exit MS Word. Is it my MS Word End Note tab? Or the End Note program itself? Or something else?

End Note X6 User

Thanks
