I recently purchased Affinity Designer on May 3rd and my purchase was accepted by Affinity and the purchase has gone through my bank. However, I also had a trial Affinity product that I placed in my Mac applications in Nov. 2019 which had supposedly expired. When I went to download and open my new purchase of Affinity Designer it tried opening my trial Affinity from November and wouldn't open my new purchase. I have tried using the old product key with the trial version and also tried using my new product key with my current purchase and keep getting an error report for both. So I guess I need a new product key along with making sure my e-mail address is correct. Please help asap or refund my purchase. Thank you, Ann L Hankel Rolph
