I heard their support is very busy right now due to Covid, the summer sale, and the recent racial justice bundle, so it might take a few days for them to answer you.
If you'd like to have the download right now, you can send an email to support@nimble.tools and I'll send you the zip as an attachment directly. You can include your key in the email as well.
