At first thanks for such a good and useful application.
There is a little bug in version 1.1 and 1.2 too: when there is no internet connection available the app crashes.
It happens on line 216 (OnlineAssetsControl.xaml.cs):
private void LocaleWorkerDoWork(object sender, DoWorkEventArgs doWorkEventArgs) { _locales = XboxAssetDownloader.GetLocales(); }
when "GetLocales" function tries to download data from "the link" (line 55, XboxAssetDownloader.cs).
