Your profile is corrupted! It happened to me too. If you still have your original profile folder saved onto your computer before you modded it.. you delete the modded profile off of the usb, and transfer the original folder onto your usb. Then plug it back into your xbox, this should work. If not PM me and I'll help you out more in depth!

Sometimes Your Dashboard theme won't appear or You will have to enter Settings for Screen Width and Size on Mw2, Or you wont see any of your profile Info or avatar, But sometimes You will see'em for a little bit then they will dissappear
