I have uploaded an alternate download for players who own Empyrion - Galactic Survival on the Epic Games Store:

If you are playing single player or coop you will need to download the scenario by following the directions in the link.
If you are joining a server that is running Reforged Eden 2 you don't need to take any action, the game automatically downloads all needed files from the server when you connect.
