Hi there, I bought Affinity on the app sore on my mac and have recently got a new desk top windows PC. I was looking to get affinity on this machine too as i know you can have it on a number of machines if its just you using it. When i go to sign into my account, it dose not recognise the email address that is associated with my apple ID. Is there a way for me to get this on both PC and Mac without having to purchase two licences Thanks!
