I have a windows 7  and using Adobe digital editions 2.0.1.  I have downloaded books for years.  I updated my ADE to 4.5 and the problems started.  I have since been told to uninstall 4.5 and reinstall 2.0.1.  I have.  I am now getting this error E_AUTH_BAD_DEVICE_KEY_PKSC12   does anyone know what to do?
