I had a PM which came through fine. I tried to reply (twice) but it wouldn't let mine go through. I don't know if that's a function of the upgrade, my OS, or something else.

I do believe it is because of your email address. If you update the email addy, it may work. I know the PPM is not coming to you via email, it is a board function to alert you when you log into the board. It may not allow you to send if the outgoing email is "unavailable", as your email is.
