Since we're in the wilds of 2019 and keys are not as eternal as we once thought they were, I need to say this:
This key is an old key. It was purchased several years ago. To the best of my knowledge, it's as fresh as it was the day it was bundle-bought. I haven't used it, and I haven't given it away. However, these days keys get voided for various reasons that are beyond our control.
If the key doesn't work, please contact me. If I can fix the issue I certainly will. If I can't, I hope you'll agree to let support delete the giveaway.
