Dungeon Master's Guide not showing in Journal

I purchased the Dungeon Master's Guide today, and already enabled it in my running campaign. But somehow it's not showing up in the journal. Like the example says on the marketplace, also none of the maps are added. Also the  eladrin race is missing in the charactermancer. The tokens are working tho. What am I doing wrong?

When you are at your game's launch page there is a game add-ons section where you can install the purchased items for the game.

Ah shoot of course I missed that one, haha. Thx

The DMG won't appear in the journal tab as a book, though if you load the addon as Jordan described, you will get a lot of the assets from it in the journal tab, such as art handouts and roll tables. The relevant bits of the book are indexed in the compendium as separate articles, many of which can be turned into handouts through drag and drop. To read through the book in a naturalistic manner, you can either go to the out-of-game compendium page , or use this Stupid Trick to read it in-game.
