problems with WWW [Solved]

hello everyone im trying to download a .txt file but i got this as result, and in my txt i only have an “8”
here is the code

WWW www = new WWW(BundleUrl + "/version.txt");
		yield return www;
		Debug.Log (www.text);
		if (!string.IsNullOrEmpty(www.error)) {
			df.text = www.error;
			throw new UnityException("error " + www.error);
		}
		else {
			Version = int.Parse (www.text);
		}

i was using a free hosting so they use a “antibot system” and i cant acces to my files from unity
