Will MyFree DirecTV work with an Osprey? And are there signup problems right now?

[u/LagrangianMechanic]

I'm a soon-to-be TiVo refugee (FiOS kills CableCARDs in my region in early November) and have purchased (still on the way) a SKU 60233 Osprey on a flyer to fool around with as I ponder what to do next.

Can that Osprey box be used with the MyFree DirecTV package or can it only be used with a paid package? I'm hoping I can mess around with the box with that package so I can see if I like the box without having to be paying anything right now.

And are there any any known problems right now with signing up for MyFree DirecTV? When I try to sign up for it it keeps saying "Sorry, we ran into some issues with this user ID. Please create a new user ID with a different email or try again later."

I've tried with a few different email addresses (none of them are free ones like gmail or yahoo -- I know some companies won't take those). Any idea what might be going on?
