CrossPlatformInitialize.cs throws an error because of this statement:
BuildTargetGroup.WebPlayer,
ERROR:
Assets/Courtyard/Editor/CrossPlatformInput/CrossPlatformInputInitialize.cs(91,34): error CS0619: `UnityEditor.BuildTargetGroup.WebPlayer' is obsolete: `WebPlayer was removed in 5.4, consider using WebGL'
I believe Unity has phased this out.
Also the install throws a minor error if you install on Beta Builds. Because the build isn't listed in it's database.
