Got a problem with lesson 1

Hey,

I'm having a problem with the lesson one, when you launch the Mazerunner prototype for the first time. I can get the engine up and running and it does say it's the mazerunner prototype, but when i try to launch the mission it says '' You do not have the correct version of the fps starter kit or the related art needed to play on this server(invalid packet).

I modified the main.cs to launch the prototype, i've added the system scripts just below the onStart function in the other main.cs:

function onStart() {
Exec("./EGSystems/SimpleInventory/egs_SimpleInventory.cs") ;
Exec("./EGSystems/SimpleTaskManager/egs_SimpleTaskManager.cs") ;
Exec("./EGSystems/Utilities/egs_ArrayObject.cs") ;
Exec("./EGSystems/Utilities/egs_Misc.cs") ;
Exec("./EGSystems/Utilities/egs_Networking.cs") ;
Exec("./EGSystems/Utilities/egs_SimSet.cs") ;
Exec("./EGSystems/Utilities/egs_String.cs") ;

Parent::onStart();
echo("\n--------- Initializing MOD: FPS Starter Kit ---------");
(...)

Can't find an error in that here, maybe i'm just blind =/.

I did add the base/data/GPGTBase, the MazeRunner/A_settingUp/Mazerunner and the MazeRunner/Lesson_001/heightfields directories in the Mazerunner/prototype/data folder like asked in the book.

I just can't find what's wrong there, hope somebody can help me! =/
