I exchanged the box this morning and they gave me another SA Explorer 2200.
I asked if they had other boxes and the lady said no, for my account that's the box they use.
Trying to activate it now but getting a blue screen that says the box is not authorized and to call 800 266 2278.
ETA: Called the number and they ended up, after trying to activate the box one way, sent some kind of a reboot signal that got the box provisioned.
While returning the previous SA box this morning there were at least four others with the same SA box in line, at least two were exchanging their boxes, as were others with different STB's.
