Second, start the game and don't go into the menu, stay in the "Press enter to start" screen, then you open cheat engine.
And this cheat table is wrong, you need the correct address to edit on your own, search for text "FRLobbyLANGame" and scan your game, then will appear FOUR address.
Those four address need to be changed AT THE SAME TIME, select all of them and change them to whatever you want, make sure you do it right as they are case-sensitive.
Go back to your game and select "free run", if you did it right, offline zombies should start.
When the game loads, pause it and open the trainer as adm, and you are good to go, go back to your game, have fun.
PS.: I did this on Steam version, I haven't tested it with unnoficial versions of the game.
