I have 6 Studio spot 575 onsite for this show. Three of them were working fine, but my LD informed me after awhile that he was having troubles with 3 of them, when I went to check all 3 were showing UPLd on the display screen. I am unable to access the menu, and when I hard reset them they go right back to the same thing. Removing data and resetting does the same thing, I am at a bit of a loss here. I have never had this error pop up and neither has my LD.
