Can't open any of the programs

Hi, The problem I have is that I had a subscription for the Creative Cloud form an online university, which expired today. I bought new subscription, made a new account, signed in it and when I try to open Photoshop or any other program it shows me the message: "Sorry, your account is not valid on this device.
