Thank you for contacting us and I'm sorry about the issue you are experiencing. The purchase of an mSecure 5 license is tied to the mSecure account used to purchase it with. There is no way for mSecure to register a license for another account to a new account or different account. However, if you let me know what mSecure account you used to make your purchase and verify this other email address, I can transfer your purchase from one account to the other. Otherwise, please provide proof of purchase and I can update your mSecure account to be a paid account.
Note: Found no account for the email address you are using on this forum.
