You maybe a victim of piracy Office 2019

In my experience, most people use M$ apps, such as Windows, Office, Teams, Skype etc.
I paid good money for Office 2019 and used it effectively for 2 years before M$ "updated" it, rendering it useless.
If I bought a car and the maker sent an update over the air which killed it, would you expect me to just buy an alternative?

Maybe I missed something but did you ever contact the place you bought Office 2019 to see if they could help you?

Do you know what PC World is?
It's a retailer that sells washing machines, TVs, vacuum cleaners, fridges, PCs and software.
A bit like Woolworth's, in its day. Any problems "it's not my counter".

No, I phoned M$, the instigators of the problem. They were worse than useless.
