Thanks.
It makes sense.
Well, as far as i know, the game loads the account data when you open it (or maybe when you hit "multiplayer" it reads the data too). So the only way for the game to read the new data is that you exit the game, switch accounts, and re-open the game (or go to main menu, minimize, switch, and enter mp). There is no way to avoid that.
If it works without exiting the game (aka, exit to main menu, minimize, switch) tell me, and i will update the info.
