I am having trouble adding a SINGLE slingbox to a second account. Multiple people in my family used to access the same slingbox. My sister, two brothers and I all have separate accounts. We upgraded from a Pro--with all being able to log in to this one slingbox with separate accounts--to an M1. My brother took it home and set it up. The rest of us are 3.5 hours away, and cannot see a way to add this. Does he have to log into my account while on the same network as the slingbox to add it to my account? I cannot use the windows app without being on the network to add a new slingbox, at least not that I can see. Help!
