I can't seem to get the packet monitor to watch for packets... I get the following stack trace:
An invalid argument was supplied
at System.Net.Sockets.Socket.IOControl(IO32 ioControlCode, Byte[] optionInValue, Byte[] optionOutValue)
at Org.Mentalis.Network.PacketMonitor.Start()...
Any thoughts on how to fix this up?

Thanks.

I get the same error when I try to use it on a wireless card. Could that be your problem?
