Windows 10: Windows 10 Pro Deactivated

So I have had Windows 10 Pro on my PC for 3-4 years and all was well. Just recently I needed word for school, and so I downloaded the student package that my school offers for free to us. Low and behold, after signing into my school's Microsoft account, to access all Words, Power Point, Excel, etc.. I have this water mark that says to activate. I've been downgraded to Windows 10 Education, and now I don't know what to do. And I don't have my original product key, what should I do. Thanks for reading

:)
