Need help in getting started with Assetbundle example

Hello im trying to get started with making use of asset bundles for my android/iOS based app. Im using unity android/ios pro version.

I downloaded the asset bundle example from unity website. http://unity3d.com/support/resources/example-projects/assetbundles

but im sure i should do some workaround before i compile the code. I ran the sample as a web player, windows standalone project but still it showed some errors when i clicked "Download Shared.unity", i get the following error..

 You are trying to load data from a www stream which had the following error when downloading.
 Couldn't open file /Users/Dell WiMAX 13/Downloads/AssetBundles/AssetBundles/Assets/../AssetBundles/Shared.unity3d
