[Windows Store App] WWW class throws exception when reading from persistentDataPath

Hi!
I'm using www class to wrtie some files to Application.persistentDataPath. All files are saved correctly. But when i try to read them, i get

Code (csharp):

1. 'myWWW.data' threw an exception of type 'UnityEngine.UnityException'

and

Code (csharp):

1. file:///C:/Users/user/AppData/Local/Packages/packagename_kx5z7px8ckg18/LocalState/filename cannot be loaded

 

This path exists for sure

 

i want to read my assetBundle like this

Code (csharp):

1.  
2. string file = "file:///" +  Application.persistentDataPath + "/"+ "someasset.assetbundle";
3. myWWW= new WWW(file);
4. yield return myWWW;
5. Assembly.setAsset(myWWW.assetBundle);

But app stops running on

with errors i mentioned above.

This code works perfectly on ios and android, but not on windows 8.1
