Fortnite Pc Rdw Error Message?

I'm a Ps4 player and now I've got Fortnite for the Pc as well. Everything works great too. But I also have Rdw (Save the World) and wanted to try it out on the PC as well. I also get into it but I can't play any games, because then comes the message: "Before you can continue, the rest of the game content must be downloaded, the game is closed and the download starts". 1. I do not know what content should be missing, because on the Ps4 Rdw still works fine and 2. When the game is closed then nothing happens. I will not see a download nor anything else.

I would like to know how to fix the problem.

In that case, I would click Verify in the Epic Launcher at Fortnite.

If you're wondering where to verify…:

If that does not help, uninstall and reinstall it.

If that does not work, contact Epic Games Support, who will respond within a few days. https://epicgames.helpshift.com/a/fortnite/?contact=1

In that sense, I wish you a nice day!
