Thank you for contacting us and I'm sorry about the issue you are experiencing. What account email address and password are you trying to change? mSecure 5 is the first and only version of mSecure to use an account system and I see no mSecure account under your email address. You'll have to create an account in order to get started with mSecure 5.
Note: this website (https://support.msecure.com) uses a separate account system meant only for support.
i WANT TO CHANGE MY EMAIL ADDRESS ON THE ACCOUNT
Why are you screaming? Why reply to a completely unrelated post? Why not create your own discussion or topic and provide useful information? What email address are you trying to change? Where? So many questions and so little information provided.
