The only difference between the two is the callbacks that get loaded from the start. OnGameModeInit, OnFilterScriptInit, OnGameModeExit and OnFilterScriptExit. It wouldn't give you error, and the "Invalid entry point" is usually caused when you haven't added the 'main()' function into your gamemode, as mentioned above by BenJackster. You could have easily ******d this problem and found a solution within seconds... but no, you people seem to shoot and ask questions later.
