XNA - Error when trying to tile a Background texture

Question

I'm practicing 2D Game Development in C#-XNA. I am trying to use a 48x48 texture as a Background, the idea is to Tile the texture to cover the screen.
But it throws an error I'm gonna show you below.
Code:
protected override void Draw(GameTime gameTime)
GraphicsDevice.Clear(Color.CornflowerBlue);
//Draws tiled Grass BG
Rectangle destGrassRect = new Rectangle(0, 0, 800, 600);
bgSpriteBatch.Begin(SpriteSortMode.FrontToBack, BlendState.Opaque, SamplerState.LinearClamp,
DepthStencilState.Default, RasterizerState.CullNone);
bgSpriteBatch.Draw(spriteGrass, Vector2.Zero, destGrassRect, Color.White, 0, Vector2.Zero, 1, SpriteEffects.None, 0);
bgSpriteBatch.End();
base.Draw(gameTime);
ERROR: XNA Framework Reach profile requires TextureAddressMode to be Clamp when using texture sizes that are not
powers of two.
And when I change the SamplerState property
to LinearClamp the
game runs but it looks like this (open this address):

Any ideas why is it happening?

Hi Juan,
This  forum is about C# language itself, you might get better answers if you asked your question, clearly, on
