Error CS0619 with Standard Asset

Hello,

When I place a FPS Prefabs in my game, I can’t test it because I have this 2 error code.

Assets\Standard Assets\Unity\ForcedReset.cs(6,27): error CS0619 : ‘GUITexture’ is obsolete: ‘GUITexture’ has been removed. Use UI.Image Instead.’

And the same but with

Assets\Standard Assets\Unity\SimpleActivatorMenu.cs(10,16): error CS0619 : ‘GUIText’ is obsolete: ‘GUIText’ has been removed. Use UI.Text Instead.

But it don’t work when I change the files.

I also Have the same problem But Cant fix it
