TrailerTrash, Did you ever get it to work? I finally allocated time this afternoon to write down all my settings in preparation for the upgrade and when it came time to download, I ran into the same problem you did. But I'm a little confused because my S/N format is simply "99000605..." with not MODEL990... in front of it as yours seems to have. I got the "Forbidden: You don't have permission to access /cgi-bin/990validate.pl on this server" error.

Don't know when I'll find the time to upgrade again and I really want to see if the upgrade fixes some of my little issues...

Thanks,

Marc
