ERROR: System attempted to load an incorrectly-formatted asset

Every time I try to play on DE Multiplayer (whether ranked or unranked) it pumps this annoying message, I don’t know how to fix it even if I re-installed the game it keeps appearing.

EDIT: It appears when a game starts, after that, I have to press Ok in order to play.
