This is the Adiro font, I can't buy it anywhere, I've been looking for somewhere to buy it or dowload it from but it seems to be impossible

Yes, the link to purchase it is broken. Have you tried contacting Summitsoft?

Yes, haven't had any response in a week. I was hoping there was another solution

Maybe a used copy of Font Portfolio on some auction site -- something like that. Sorry, I can't
think what else to suggest.
