The QR code is only sent out one time when your account is first set up. We don't have the information necessary to construct that code, so there is no way for us to send that code.
Can you let me know what has led you to this place where you need help? Please provide all the context you can about what is happening, because if I can understand everything that led to the start of the problem you're experiencing, I should be able to help. For example, are you trying to upgrade to mSecure 5 from the old mSecure app?
