It appears you’re using different email addresses. One @aol.com, one @probably-your-employer.com . Also, you used to use a address of the form, if your name is ‘John Doe’ as ‘firstname.lastname@example.org’. Then, when you were prompted to start the registration process, you used ‘email@example.com’, and then ‘firstname.lastname@example.org’.
Most likely, you were using AxCrypt for the first time on a new computer, and entered the wrong email address.
Your original, verified, email account is thus of the form ‘email@example.com’ (substitute your own first name first letter and last name of course).
