Hi @kaoer,
We partnered with PixelGrade to offer Hive on WordPress.com. If you purchase the theme directly from our repository, then it can only be used with sites that are hosted here.
If you’d like to use the theme on a self-hosted site then you’ll need to purchase a separate version directly from PixelGrade here:
Pricing
If you’d like to be refunded for the WordPress.com theme then let us know within the next couple of days and we can help with that. As part of the refund, the theme will be removed from your site so you wouldn’t be able to continue to use it as a draft.
Let me know if you’d like to go ahead with that refund!
