Can´t create/launch project from Launcher or UProject. [MAC]

[Selbryn]

Good Evening,

I was working with my cpp project (I am working on a Multiplayer game), creating a new GameMode (cpp not blueprint), and exposing some functions to the blueprint. I closed my project to launch a client window with this command.

#!/bin/sh

cd ../Shared/UnrealEngine/4.10/Engine/Binaries/Mac/

open UE4Editor.app --args "/Developer/BloodAncestors/BloodAncestors.uproject" -game

After close the project (without errors) I starting to have errors.

1. I can’t create a new project from
   Launcher.
2. I can’t open an existing
   project from Launcher.
3. I can’t open
   an existing project from UProject.
4. I can’t launch my game with this
   command.

When I press over one project inside the launcher the launches goes to the background but nothing happens.
