You didn't buy the software; it came with your computer purchase for use on that computer only. The computer manufacture modified it or had it modified for their specifications.
It is typically not upgradeable but you can sometimes qualify for a discount.
You live in a real world! Even though you don't like it. Complain all you want but that will not change things - sorry.
Did you talk to your computer manufacturer as I asked?
You said that there were no changes to your computer ; not even Windows updates?
If this just started happening, use Windows restore to restore your computer back to the time when it worked. Start adding in the Windows updates and other new programs, updates, etc until it stops working. You will have figured out what caused the problem.
