I downloaded and purchased EXver2.0 as a one-time purchase upgrade from clip studio pro at a discounted price, but the license display has disappeared and I cannot use it. The purchase confirmation email was from an address that I cannot currently view, so I changed it after purchasing, but was there a required procedure in the purchase confirmation email? Is it possible to resend the email?
By the way, even if I go back to ver1, I cannot authenticate the license and I cannot work at all.
In the notification of the launcher of Clip Studio Paint, I received a message saying "Thank you for purchasing EX2.0", and the order history on the account page of Clip Studio Paint shows the payment completion history.
I think the purchase procedure itself has been completed, but how can I use it?
Thank you in advance.
