When I drill right down to the very core of the code which produces this error, it transpires that the error is produced when a connection has been made in the first instance, but the connection did not delivery some/any of the data that was expected. This is normally due to a firewall instantly blocking the communication it has detected as unauthorized, but can be caused by ANYTHING that will step in between the AppGameKit Compiler and the devices you have on your network. Given case history, it is definitely not a bug in the traditional sense, but we are looking at all the myriad cases where such communication can be interfered with. If you do find that switching off some essential background task or reconfiguring your network settings solves this issue, let us know so we can add the details to our AppGameKit FAQ.
