I've bought some time ago(3 years) a key for Vegas Pro 14 through the Humble bundle by Magix. It was activated and used once in a while. Now I got some new PC and when trying to reinstall, it asks me also for the email address once giving the activation key, then it prompts that the key was activated on the different email already. Is there any way to reset this email attached on the Magix servers? I must have put there some email address I don't remember anymore.
