This contradicts the other answer from your colleague.
What's the point of reinstalling the software if there is no way to reactivate it?
I just came across a file corruption issue and the best solution I could think of is reinstalling.
I paid for the software and I would like to keep using it as it is. I don't really need the product that got discontinued. But if a computer dies I won't be able to install it in another one even if I have a valid license? (which was not cheap if I may add)
