I have the same error that azurfire initially did, as soon as I begin connected to N WFC, I get "communication error, please turn off power". I believe I have entered everything correctly, including the DNS (the primary and secondary have to be the same right?) and my .pkm file is fine. I've also done everything in the python correctly because it says "Ready to Send..." Help?
Also RedGalaxy thats an error due to pokesav usually, make sure its "nickname" is same as its pokesav name instead of just blank when you create it.
