Ugh. What a stupid mistake on my part, and I was thinking before I did it that I would need to use my other email address. A friend serves as a relay (and I for him), but he's not where he can access it either. Perfect timing. I need it back up and running today if at all possible, so I guess I'll purchase a key using another USB stick, too. Been wanting to make a second, smaller box , so I guess I'll be buying that key early. When I get the other key in I can use that, too.
Again, thanks for all your help here.
