I need help - License Key - Steam

I bought glasswire using steam a few months ago and I had to factory reset my computer, now I can’t use the same license key because I forgot to deactivate glasswire before resetting my computer. How can I manage to use the same license key once again if I don’t have access to that computer anymore?
