SplashScreen Problem

Hi, i want to create a splashscreen using the PlatformerDemo. I followed through the tutorial from this url http://tdn.garagegames.com/wiki/TorqueX/SplashScreen#Creating_the_Splash_Screen but i encounter problems such as "cannot implicitly convert type 'Microsoft.Xna.Framework.Vector2' to 'GarageGames.Torque.MathUtil.SizeF' and The name PlatfomerStarter' does not exist in the current context'. Im not sure what it means.Could anyone help??

//using PointF = Microsoft.Xna.Framework.Vector2;

using GarageGames.Torque.Core;
using GarageGames.Torque.Sim;
using GarageGames.Torque.GUI;
using GarageGames.Torque.MathUtil;
using GarageGames.Torque.T2D;

namespace GarageGames.Torque.PlatformerDemo
{
class SplashScreen : GUISplash, IGUIScreen
{
//======================================================

public SplashScreen()
{
// create the Style for our splash ad
GUISplashStyle splashStyle = new GUISplashStyle();
splashStyle.FadeInSec = 2; // black to image 2 seconds
splashStyle.FadeOutSec = 2; // image to black 2 seconds
splashStyle.FadeWaitSec = 4; // still image for 4 seconds
splashStyle.Bitmap = @"data\images\nice";
splashStyle.PreserveAspectRatio = true;
//splashStyle.Anchor = AnchorFlags.All;

// set some info for this control
Name = "SplashScreen";
Style = splashStyle;
Size = new Vector2(800, 600); // Changed System.Drawing.SizeF to Microsoft.Xna.Vector2
OnFadeFinished = OnSplashFinished;

// create a black letterbox
// only visible on widescreen displays
GUIStyle lbStyle = new GUIStyle();
lbStyle.IsOpaque = true;
lbStyle.FillColor = Color.Black;

GUIControl letterbox = new GUIControl();
letterbox.Style = lbStyle;
GUICanvas.Instance.LetterBoxControl = letterbox;
