Reinstall VVVVVV if you bought it from the site?

[Fiefen]

So I bought VVVVVV ages ago, as a download from the main site (not from steam or anything). I recently upgraded my computer software, and some certain things, including VVVVVV, have dissapeared. How do I redownload it without having to purchase it again?

Search your inbox for VVVVVV! You should an email somewhere with a download link, either from humble or fastspring!

Thank you so much!
