a) Look at your spam filter. After my problem was resolved, I received other mails by Dave, all of them went straight to the spam folder on my mail server.
b) Check your account at maemo.org if you're using more than one mail address. AFAIK, they sent it to one of the additional addresses this time, not to the main one, if a user has more than one address registered there.
c) email Dave, the sender of this mail. (Just don't want to publish his address in too many places... ) - He always helps.
