Hey Tidal,
The error you're running into when trying to use TCP packets *usually* indicates that you need to install WinPcap. We've got a bit of documentation on this, which you can find here:
http://www.pingplotter.com/manual/raw_tcp_sockets_and_winpcap.htmlIt takes a bit of configuring to get UDP packets working as well. We've got a knowledge base article that can help out on this front as well:
