Office 2016

[leo1231365]

I am new to the forum and would like to ask for your opinions. 

I am using office 2016 and decided to login my 365 account.
After a few days, the word app is asking me to reactivate my license. 
Whenever i open a word, excel or ppt files, it opens with 365.

Changing the open with office 2016 properties of files is not working. 
How do I revert back to using the office 2016?

Then locate your Microsoft Office 2016 application and then click on Change and repair it.
