Hi Shem! Modules can only be used to create a game; they cannot be added to existing games. This is by design, to keep users from creating unmanageably large games. Addons can be added to existing games, and they are typically much smaller. Their main resources (journals) can also be reasonably easily removed as well, since they are typically contained in a top level folder. Pro users have access to the Transmogrifier, making moving assets between games easier, but this is not a solution for moving an entire module. Basically, create a new game and move the characters. You'll wind up with a much more efficient and responsive game.
