www problem

Hi Guys.
i have a problem :

SecurityException: No valid crossdomain policy available to allow access
UnityEngine.WWW.get_text () (at C:/buildslave/unity/build/artifacts/generated/common/runtime/UtilsBindings.gen.cs:208)
Parse.Internal.HttpClient+<>c__DisplayClass10+<>c__DisplayClass16.b__a (UnityEngine.WWW www)
Parse.PlatformHooks+<>c__DisplayClass24.b__23 ()
Parse.PlatformHooks+d__2e.MoveNext ()

This is a security feature built into the www class. You can read about the problem and the solution in the Unity docs here: http://docs.unity3d.com/Manual/SecuritySandbox.html
