Activation Key

Hello,
I was in Senegal for 6 months soon after I purchased DavinciResolve 16 Studio.
On my way back I left the box which has my activation key, but brought my dongle with me. Tonight in the middle of my project, it stopped responding, asking me for my activation key, which I do not have.
What should I do? Please help! I am close to a deadline!
