2,4 Error
 

Problem:

2,4 Error is a stats error that causes your age of Myhtology game not to correctly deliver information to the Ensemble Studios Server.

This error will cause your stats to remain at the same rate forever, meaning that if you loose 10 games in a row or win vs a 1900+ player, your freaking stats will stay the same.

Go on internet forums and  find the patch, I suggest googling aom heaven 2,4 error stat fix
