"For commercial use of fonts, a nominal donation of the cost of two imported beers is all I suggest for full usage of a single font. Sounds reasonable, right?"
Have you clicked through the Donate button and made a donation? In doing so, you can pass along a message asking for clarification that you are allowed full licence for commercial use of the font, but the above, from the authors profile page seems pretty clear (and perhaps you could prompt them to update their email account at the same time)

Amazing advice! Who doesn't love beer! haha. Thank you so much for your help x
