A user account is systematically created each time a purchase is accepted by RegNow.
This account has your RegNow user name as login, and the email is the one you declared to RegNow. You can thus get your password with the "If you have lost your password, click here" in Users top page by providing the same information as to RegNow.
Your account contains the version that you bought together with all the new versions that you are elligible to.
NB: your account is created within one business day of the purchase.
