halo reach problem

i have reach and i cant play online but i went to my friends to get the update and i played reach with the internet still connected and now i only get 50 cR/ thing i do max
is there any way to reverse this/ fix it
(i cannot play live at home i dont have gold or a connection for my xbox)

I get what you mean... the answer is no. As soon as you play reach online you can only get 50-60cR a game offline.
