How do I play Gears of War online?

[ShawnD1]

When the game starts up, it signs into Live. If I tell it to go online, it gives me an error saying my key is invalid. That's strange since it never asked me to enter my key in the first place. I've already played through the entire single player campaign and it has not asked for a key. I don't see anything in any of the menus asking me to put in a key.

Seriously, where do I enter the key. This is starting to piss me off.

Have you tried to enter your key into Windows Live? Might hunt around for the option.

That's probably where I'm supposed to do this, but I don't see an option there either.
