Plug-in download problem

I am having difficulty downloading the InControl plug-in for Windows Phone. I am trying to download from the Updater in HS2. It looks like everything has worked fine in the web interface, but on the console, it is getting a HTTP 404 error, file not found. When I restart Homeseer, of course the installation fails.

System is a HomeTroller S4, running HS2 Pro, V 2.5.0.57.

Thanks for your help.
