Bought a 5e Module to add to my game, but it doesn't show up in my game add ons.

Any help/ideas please?

What Module is it?

Once you purchase it, you will have to go into the game details (click on the game name not launch) and scroll down toward the games forum.  There should be an option for "Game Addons >"  If you click that you can add the Module to the games content.

If it is labeled as a Module, then you can only select it as a new game.  If it is labeled as an Addon, then it should be in the Game Addons section as mentioned above.

That said, Andew o., if you just want to add some content from the new module into your existing game, you can create a game with the new module, and then use the Transmogrifier tool (a pro feature), to move maps, handouts, and characters from the new game into your existing one. It's somewhat inelegant (you can't move whole folders at a time), but it gets the job done. That's how I slotted a Candlekeep Mysteries one-shot into my Storm King's Thunder campaign, anyway.

@Kilter Princes of the Apocalypse @Kraynic that explains it i think. I'd bought Saltmarsh, and thought that as that could be added this one could. @Sarah I'll give that a go if all else fails! Thanks all.
