halo 4 and my profile? a little help

So i received Halo 4 last night and it keeps telling me its unable to write my gamer profile and to make sure its not on a storage device with low space. I have 182GB left on my hard drive. What do i do?

I am having the same problem. I did copy my profile over from my other xbox to my new one with a usb drive but I moved it to the HDD. I have over 180 gb free, and I am getting this too.
