ivra - load up Steam and go to the store page for Original Sin itself. Below the screenshots in the area where you can add it to the cart, you should see a green "you already own this game" area.

Now go to the new DLC's page (linked from the page you're on) and see if it says the same thing. If it doesn't, Steam doesn't think you own it yet and that's likely what is wrong. Yesterday I didn't have own the DLC, and today I do.

(I'm Canadian, so I don't think it's geographic.)
