MS Office 2016 not working after update mac os X el capitan

Ok, peeps, I couldn't find exactly any way to get this to work and thank goodness it happened after finals.

I got the MS update prompt and have been using MS Office 2016/O365 from my college for the past year.

It was working up until last night when I made the mistake of installing the updates.

I've seen a couple posts on this and tried to find the solution to get office to work, but I still haven't got/found a resolution to get office to work as it did before the updates and I need to get my resumes updated.

Here is the error message:

Currently running Office 2016 version 15.28 / Mac OS 10.11.6

I've re-installed the office software 3 times and it still keeps throwing the error.

Can someone please point me in the right direction to get this working again?

Thank you so much for your help
