Level / Rank doesn't save.

I'm 10th prestige and level 1 on AlterIW.

I ran this unlocker.
AlterIWnet Unlocker

And obviously, it unlocked everything, played 3 games, exit, started again, and now I'm 10th prestige level 1 again :/.

What do I have to do to make it save?

Go into your players folder, and delete all the STAT Files.
Then create a class or something, and it should save.

what he says ^
but you need to play a full game after you edited your stats

Or put lvl 69.999 and make one kill stats will be saved
