Locked myself out of all access databases

I ran the security wizard, which baffled me, and now I can't log into any of my access databases.  Access prompts for a username and password no matter what db I'm trying to open.

You've joined a workgroup other than the Default system.mdw file. You need to open Access (don't open a database), then click Tools - Security - Workgroup Administrator, then click Join and find and rejoin the system.mdw file.

Just to explain a bit; Access user level security is always "on".  The default workgroup file and any newley created workgroup file has an admin user with a blank password.
  JET tries this login when first opening a DB and if it suceeds, you don't get the login prompt.  If the admin user has a non-blank password, then you get a login prompt.
  That's why part of the process of securing a DB is setting the admin users password to a non-blank; it activates the login.  It's also why you remove the admin user from any of your security groups.  If you did not, anyone could get into your DB by setting the admin password to a non-blank and then have full access.
  Last, normally when you secure a DB, rather then chaning the default workgroup, you would use your custom workgroup file with the DB via the /wrkgrp switch when using starting Access.
