Every time I open up IW4M, I have to redo everything: from classes to titles. My level and my prestige stays the same, everything else just vanish.

I've done a fresh install but I haven't solved the problem. If I play a couple of matches (to get the stats saved) everything seems ok, but when I go out and then back in, boom. Nothing again.

What to do?
