Failed to load map?

Hi guys! My friend recently sent me his game’s project, and when I try to load it up, I get this error: “Failed to load map!
.umap is a UE4 map [File:v498], from an engine release newer than this [Cur:v482].”

I’m guessing that this means I have an outdated version of Unreal, but what version exactly do I need to load this?

Additionaly, I’m also unable to load any of the .uasset files in any other projects. I have tried placing them in the Content folder via File Explorer, but they don’t show up in the editor - even after restarting.

EDIT: I’m using Unreal Engine 4.10.2 right now.

Bump. Hoping to get an answer soon…
