Hi. Me again, talking more to myself.
I uninstalled and reinstalled AT again and now it's seen as installed on the web portal. But this time, it's not a root installation, because, I think, the installer never prompted me for it. The Hard Reset Protection/Store Settings link is grayed out, so I can't do that. I don't even see where I can indicate that I want it installed as a root installation. I suppose I could go through this all over again, yet another time.
Again, I like what this can be. But if someone like me has this much trouble with it, then a whole lot of other users will, too.
