Neither. He can load the game, he just cannot reach the "New Game/Load Game" screen.
You misunderstood something - there is no "new game/load-screen" that can be reached, there is only the titlescreen that includes those commands, and that screen should be automatically there on starting the game.
Unless of course you're using plugins to change the way the titlescreen behaves, and in that case we need to know which plugins you are using (with links to their websites) and how you configured them, because in this case the most likely cause is that you made an error configuring those plugins.
And you need to ask him if he understands that - he might be reporting an error that isn't there because he assumes he could go back to title screen when there is no direct way to do that short of abandoning the game.
Please ask him what buttons and options exactly he presses when he tries to get back to the titlescreen
