AssetBundles not downloading problem

I have been trying to get asset bundles to work on WebGL using the new system from this video: Unity5 New AssetBundle System

I went through my project and marked all my assetBundles. I'm not using variants.

I use this code to build my asset bundles:

 BuildPipeline.BuildAssetBundles("WebGL",BuildAssetBundleOptions.None,BuildTarget.WebGL);

I then attempt to download my manifest file so I can find dependencies

 IEnumerator ManifestSetup()
     {
         WWW wwwManifest = new WWW("http://www.featuresandbugs.com/waterford/WebGLAssetBundles/WebGL");
         yield return wwwManifest;
 
         if (wwwManifest.error.IsNotNullOrEmpty())
         {
             Debug.LogError(wwwManifest.error);
         }
 
         AssetBundle manifestBundle = wwwManifest.assetBundle;
         if (manifestBundle == null)
             Debug.LogError("No manifestBundle found");
 
         //string[] assetNames = manifestBundle.GetAllAssetNames();
         Debug.Log("asdf");
         Debug.Log("Name: " + GetCurrentPlatformBundleData().name);
         manifest = manifestBundle.LoadAsset(GetCurrentPlatformBundleData().name) as AssetBundleManifest;
         Debug.Log("Unload Time");
         manifestBundle.Unload(false);
         Debug.Log("Unload completed");
 
     }

I make a WebGL build and build my asset Bundles in the same project and version of Unity3d. I upload my asset bundles and build to the same folder on the same server. When I go to this link http://www.featuresandbugs.com/waterford/WebGLAssetBundles/WebGL my WebGL file downloads just fine.

"When I run this on Chrome or Firefox I get three errors:

(Called from my code): Invalid Unity Web File (Decompression Failure). URL: http://www.featuresandbugs.com/waterford/WebGLAssetBundles/WebGL

(UnityError): The unity3d file is not a valid AssetBundle. (Called from my code): "No manifestBundle found"

What can I do to get a proper download of these files? Thanks for the help!
