Me respondo yo mismo, copypaste del forum de Battlefront:

Update, Friday March 26

Unfortunately the scripts that run the Battlefront.com store and digital downloads are not running correctly on the new server. Such problems are, unfortunately, normal for software of this complexity. Which is why server migrations are usually done over several weeks if not months, not attempted with only hours to spare. Everything that can be done to get the store and digital downloads working is being done. Sleep is not an option.
