Microsoft Office 2016 “Need To Activate” | Mac

Hello. I have a 13″ 2016 MacBook Pro with the Touch Bar. I got Microsoft Office the day I got my MacBook, which was back in June. I installed and activated Microsoft Office that day. However, now that I am using these programs, I keep getting the message, “You must activate your copy of Office for Mac within X days.” The message will have the options “Activate Now” and “Activate Later.” However, every time I click “Activate Now,” nothing happens. I looked online for a solution, but I do not feel comfortable deleting files on my laptop knowing that I could possibly make the situation worse. Is there anything else I could do? Now I only have one day to “activate” my copy of Office… Thank you in advance.
