Do you have to buy the content from the Acquisitions incorporated book for it to show up in character creation? It was released for free a while ago with the merger and I can't seem to access the race, class, backgrounds, or magic items in character creation. If anyone could help out it would be much appreciated. 

The Acquisitions Incorporated book was made available to claim for free for a limited time, it wasn't made automatically available to everyone. If you didn't claim it during that period, you will need to purchase the book to access the content.
