That's good, you've promised to back it up. Don't forget.
Next question : are you quite sure you did buy Transcribe! ?
After all, you've looked for the registration email and not found it. I do sometimes get requests for reissued licenses from people who never bought it in the first place. This is a waste of their time and mine. I only reissue licenses to people if I do find them in the orders database.
