Well, my progress keeps deleting.

First, I played multiplayer and made it to rank 5. After that, I went to do a little campaign work and start my first play through. I made it to about the fifth mission, saved, then turned it off for the night.

Next day, I wanna do some multiplayer. I turn it on, and I see that my rank is reset to default, and everything I had unlocked was gone.

I was pissed.

Now, I'm rank 14, haven't played campaign for a few days. I wanna play some tonight, but I turn it on, and see that ALL my campaign progress has been deleted. I go to New Campaign and see on the right-hand side that everything has been reset to zero.

Does anyone know, or have had this problem before?
