Strange thing is that when I went into the preferences, I found all the alerts were checked, but I wasn't getting the notifications. Just for grins, I clicked on "save" and then I started getting notifications again.Joe had the same issue, he was able to get it ironed out by going into the notifications section and click save changes, without actually changing anything.
You could give that a try.
I got the charge board for my computer and installed it. All is well! Hallelujah!
