Can not install new channels on my jailbroken ATV2

Hello everyone,

i would really appreciate it if someone can guide me through on how to resolve my problem, i can not see any new channel that i installed, im having a jailbroken atv2 version 5.0.2, and whenever i install a new channel, it says installed, but i dont see the icon on the main screen, and i also can not receive any new channels from apple, maybe that because im running an older version than what is required, but what about the other application ?

H E L P !!! Anyone :(:(:(
