How to stop pop-up re MS Office is not valid?

[de6lab]

Every time I open Microsoft Office a pop-up stating that my program is not
valid and it has Microsoft Advantage which takes me to microsoft web site
wanting to sell me an updated and valid program. I am feeling harassed by
this and would like to get this pop-up off my M.O.

thanks for any help

Buy a genuine copy of Office instead of a pirated one.
