If the Member Zone password you set up was validated using a uscg.mil email address (that is, your primary email address listed in AuxDirectory/AuxOfficer is your.own.name@uscg.mil, then you may not be able to configure either WOW or the Public Education Database. Currently, 0.37% of Auxiliary members have uscg.mil email addresses.
The reason is that AuxOfficer categorized you as an active duty member when you applied for the password, even though you are a member, starting fall of 2011.
If you fall into this category, simply revisit the AuxDirectory/AuxOfficer sign-in page, and from there request a new password (it can be the same one) using "Obtain/Change Password". Or, just click this link.
