As nobody responded, I'm going to temporarily assume that nobody has tried to do this before :)

If that is indeed the case, could some kind hearted person please try opening one of these versions, exporting it out as a Windows Store project, opening it in Visual Studio, and then successfully run it?
By looking at the project you can see that all it's trying to do is connect to the Scirra multiplayer server. Testing the program within Construct, as well as running it as a desktop or html will connect immediately. However, as soon as I try it in Visual Studio, it fails to connect.
I have been in contact with Microsoft about this for weeks, and they can't seem to find out what the problem might be. I have no idea whether it's an issue on their end, a setting I've failed to turn on on my end, or an error with Construct 2 and 3.
Please could somebody help me out?
