Failed to open map file. (Bull Cow game)

[pmorizzle]

I apologize if this has already been posted but I searched using my error code and couldn’t find anything similar. I am trying to load the Bull Cow game and I get the following error:

Failed to open map file. This is most likely because the map was saved with a newer version of the engine.

When UE opens (I’m using version 4.21.2) after that error message, it is essentially an empty scene/project. No items in the outliner besides “Untitled (Editor)” and nothing in the content browser.

I’m using Windows 10 on a PC, btw.

Any idea how to fix this? Thanks so much for any help!

You would need to upgrade to a version above UE 4.21. The Bull Cow Game was built in UE 4.22. So, it will only work on version above UE 4.21, that includes 4.22 also.
