nitotv and plex not working with 5.1.1 & atv flash

Hi, 

 

nitotv doesn’t seem to be working, the app appears but when i go into the app it doesn’t show anything to install. i have intalled it through atvflash, and SSH and removed and reinstalled. 

 

I also tried to install plex through ssh and it doesn’t show the app at all. 

 

any help on this?
