Jailbreak/NitoTV help!

I hope this is the correct area as I have just joined this forum in hopes of some help. I recently just got an atv 2. I jailbroke it using Season Pass, which I know to have worked because I went through all the prompts correctly, and I see the FC logo on my TV. After set up and when I bring it back to my computer (Windows) I open Nitotv, initially my ATV shows in the list, when I hit select, it take a minute then tells me that my ATV is not jailbroken and to jail break it before I run Nitotv. My ATV disappears from this list and does not return until I bring it back and forth from the TV to the computer again. Could someone please tell me why this is and offer some help as I am out of options!
