How did you register?

by xbox 360 or xbox.com

because when you sign up through xbox.com you wont be able to sign in unless you are 18

but because of the family settings microsoft made it so anyone can sign onto the xbox.com  and if you messed the registeration up totally then you can fix that

go to dashboard sign in

go to the purple panel

all the way down it should be called intials if not then ill go on my xbox 360 and tell you exactly the name of it

but what it does is it resets the xbox 360 and takes you back to the registeration panel

ull need to create an account again

wait do you have xbox sliver or gold service

if sliver you need to subcrive to gold to get that feature i think

i have gold and i had no problem signing in to xbox.com

hope this helps

you mean you want to play xbox games or xbox 360 games?

well if u mean you arent able to play i can fix that for you

heres how to fix it

Start from the System area of the Xbox Dashboard or-if you're using the Xbox 360 system for the first time-from the Initial Setup Complete screen. Select family settings, xbox live controls  and sign in using the password for your Microsoft Passport Network account.

When you sign in, the system will load your child's profile (or, if there is more than one child profile, you'll be able to choose from all available child profiles). But the Passport Network account password you will need to provide is your own.

Select online gameplay , xbox 360 online games.

Choose one of the following settings:

Select allow to allow your child to play Xbox 360 games with others on Xbox Live.

Why not just use an wireless connection?

Hmm well i dont see a problem with taping the back but you should use duck type

make sure not to push it too tight and just do enough to keep it working

ussally that never happends but if the back is just coming out just tape it if its broken

I think the game play could be better

you should be able to have head shots from the sniper i mean come on it takes two sniper shots in order to kill the other player

there shouldent be any glitches in the game cause that just is anoying i seen people who do them and they fall under the level and theres no way to kill them which makes the game no fun

besides that i say gears of war is alright im not trading it in though cause most retailers dont give you money just credits which is not cool

Yes you can

you can even use the microphone connected to the controller onto the computer it even works with pc games with voice chat

How to connect

If wired use you're usb that came with the controller and connect it to the pc

The pc will detect it immeditally and install the driver software

if wireless

that you need the Wireless gaming adaptor
