I'm terribly sorry, but I've spent far too much time trying to restore a backup -- not due to my sloppiness or mismanagement but because my phone completely reset. It lost everything. Including my Msecure information.
I'm thrilled my data is secure but not so much that I, myself, cannot retrieve it without hours of effort and no one to call -- that I can see to help me. In fact, your ReadMe Content in MBackup states the following: "
Thank you for contacting us and I'm sorry about the issue you're experiencing. I'm not sure I understand the issue with the firstname.lastname@example.org email address. Simply type that in the TO address in an email you create to send our support an email. You can also always use this website to create a support ticket or use our forums. I'm not exactly sure what you are trying to do. Do you have mSecure on your computer (not mBackup)? If so, what version of mSecure are you using?

Please note that you need mSecure on a device in order to restore or view your information. mBackup is a really old backup utility that allowed customers to create .mscx backup files directly from mSecure 4 on their mobile device to their computers.
