Actually, I believe Module assets can only be accessed in the Module. You have two options for using them in other Games: 1) start the other Game with the Module as a base and remove any content you don't want to retain in the new Game 2) start a new Game, then open a game based on the Module and copy graphic assets from it (select, ctrl-c/cmd-c) and paste them in the new game (this only works for graphics).
