Howdy Tim,
Mark switched the installation program that Notation products use, and the "auto update" doesn't work using the older version to update to the new one. I've emailed you privately with the link for downloading your registered version (no, installing the Trial version won't morph you to the new paid version).
The reason you were unable to download from our Redownload page was that you are registered using a different email addy. If you want to change your registered email addy, you can go to
www.notation.com/ChangeEmail.php and change it to whatever you want.
ttfn,
Sherry
