Campaign Stats Erased

[FireFox516]

About 45 minutes ago, I loaded the game up as Player One with my brother in his GamerTag as Player Two. In the opening menu, the game asked to adjust my brightness, and then where my name should have been shown, it said NOT CONNECTED instead. When I looked at my Multiplayer Character/Weapon Page, everything was at default, and when I checked my stats, my entire Campaign had been deleted!

This includes all saves, checkpoints, chapters and even difficulties! I had just beaten the game on Insane Arcade this last weekend and now I have to start everything over from scratch as well as getting all my collectibles again. I've had this exact same problem in the last two Gears games, which really disappoints me, but I was wondering if any of you have had the same problem and know of any solutions? My other stats seem to still be there, but whenever I do something in multiplayer I've done already (like execute enemies with a certain weapon), that little ticker pops up with a "0 / whatever number it needs," so it kind of worries me.

Any solutions/help would be great!
