Due to unforeseen technical difficulties at BioWare, Game Update 2.4 was accidentally released today, September 30. Many people may have already started and finished their upload. If this happened and you choose to login, you will need to reinstall the entire game again. If you closed the launcher and did not open the game, DO NOT OPEN THE LAUNCHER UNTIL TOMORROW AFTER THE PATCH. You will still need to re-download GU 2.4, but at least you will be spared from having to reinstall the entire game.
