I have ports 53 and 80 forwarded on my router & static IP but it still says they are closed when I go to port checker.
*(Port 80 is apparently open now)
M@T's program actually gets me in the GTS but a few seconds later I get the message of
"An error occurred while attempting to communicate (00000) Please turn off the power, restart this DS system, and try again.
If this message keeps appearing, please contact Nintendo Consumer Service."
