Hi! I'm a fashion design student and my school provides us a wide range of Adobe programs. I asked for the Redemption Code and I've got it but when I try to enter to the school account it sais this code has already been used however the Photoshop and Ilustrator that I already have on my Mac do not work. Before starting the school pack I used a free version and so now I see that my free version is over but I can't use the school pack that I was given. How can I start using it?
