ValueError: too many values to unpack (expected 5)

Using the DCC receive example with modified code:

def on_welcome(self, connection, event):
		self.connection.privmsg("NickServ", "IDENTIFY <PASS>")
		self.connection.join("#THE.SOURCE.NOSPAM")

	def on_privmsg(self, connection, event):
		self.connection.privmsg("TS-APP|US|P|39503", "xdcc send #169")

Update: I've changed the code from command, filename, peer_address, peer_port, size = parts to just referring to the index value in the parts list which works, however I'm now getting a irc.client.DCCConnectionError: Couldn't connect to socket: [WinError 10049] The requested address is not valid in its context

I don't have access to main.py. Can you provide a bit more context?
