Ugh, no luck with my DS. But I had another idea! I used the PokEdit GTS Menu (found here: http://www.pokedit.com/gts/menu/) and it worked! All you have to do is put in your friend code, upload your .pkm file and change to PokEdit's DNS. It's pretty easy. If it doesn't work, your FC is probably wrong. Click the little "i" next to the it and click "change to it" and try again. Hope it works!
