I bought and down loaded a game and installed it. Now it says that the current profile is...

What game are you trying to download and where are you located geographically?

I misspoke, and we are going in circles; that is the same device I bought, inserted, and am currently trying to install the game on.

With my flash drive, it did say I couldn't use the device. However, it did allow me to begin saving with the internal hard drive. And, as I said, it begun installation, got half-way through, and then the loading bar actually reversed until it was down to
nothing.

It will begin installing on the drive, last for a few seconds, and then bring up the message to choose a device to install the game on.

downloaded all the new game, now installed but it asks to enter the profile you bought the game access the profile you bought the game and still does not work !!!

I just bought Call of Duty Modern Warfare and every time i tried to install one of the packs it says installation stopped. When I try to install again it gives me an error code and it says it might be corrupted. All of the packs are installed on
the external except for one and it doesn't let me transfer it to the internal drive.

you need to restart the down load that should work

Either the current Xbox Alert that gaming is limited is preventing any of my games to load, or this install severely broke my system. I can't play any games now and all of them get stuck on the loading screen.
