Lost modern warfare multiplayer data

I've been playing the new modern warfare online for a while now no issues at all, now I've turned it on to play and the game isn't installed on my Xbox at all and when I have re installed it all my online rank and data is gone, anyone know how I can get
it back I'm sure there is a cloud storage for it, but every time I go into multiplayer it takes me back to stage 1
