Alright, so I usually use my Xbox to watch videos that I have on my computer and I use the Windows Media Center a lot. But a week ago it stopped taking any controller input. My xbox would connect and not have any problems bringing up the center but when I get in it wont let me go through the menus. I've tried disconnecting it and reconnecting it but that didn't change it. Also Its not my controller because the xbox guide button still works and I can scroll through those menus fine even when I'm in the Media Center. Any help would be appreciated.

Thanks.

So I just downloaded the first Halo and whenever I try to play the game an error comes up that says "The game could not start, please download it again." And so I downloaded it again and it still didn't work. Also I used to be able to play Xbox original games that used a disc on my 360 before i got the single red light that means something isn't plugged in right and it was my HDD. Then after I fixed that I could play any Xbox original game any more. Anybody know how to fix this or if there is even a possibility of me fixing it?

Thank you in advance.
