Unable to load Unity iPhone examples as scenes

Hi,

I've been having a problem with the Unity iPhone examples. I have loaded all the different Unity iPhone example projects, only the multiplayer mpStarTropper.unity file actually loads a scene and has a list of game objects in the Hierarchy view. Roll-a-Ball, iPhone-Match, StarTrooper, TunnelRunner, OcclusionCulling and NativeCodeExample all produce empty scenes, and the hierarchy view is void of game objects even if I go to File->Open Scene to select the Unity iPhone scene and load it...

StarTrooper has the following error message: Assets/_Scripts/PlayerControls.js(31,24): BCE0018: The name 'Touch' does not denote a valid type. iPhone Roll-a-Ball has error: Assets/Scripts/Controller.js(28,31): BCE0019: 'acceleration' is not a member of 'UnityEngine.Input'. NativeCode Example has message: Rebuiling GUID cache: Deleting metadata library/metadata/cd/cd64b75bebc7342578e1e9698ebb7bfe because it is an invalid meta data file! MetaData class can't be loaded Occlusion Culling also gives error: Assets/_Scripts/iPhoneAnalogSticks.js(33,29): BCE0018: The name 'Touch' does not denote a valid type.

_MatchGame.unity has no errors but it doesn't load a scene

I'm not having trouble loading example scenes for Unity 3.3.0f3. I'm using version 1.7.0f1 Unity Pro and iPhone Advanced license package.

I appreciate anyone's suggestions so I can check out some working sample code on the iPhone.

thanks, elizabeth
