I was in the middle of my stream and my USB disconnected and when I reconnected it, the n3DSviewer told me I had to enter my product code and I no longer have the code for it since I bought it back in April 26,2015. I sent out emails and PMs to admins and hopefully reaches them! Thank you for the read.

From the date you bought it, I'm sure that you bought it straight from Keity in Japan.
So you got originally the key from them.. not from here..
