o.O Ok.
Step 1: What DS do you have? I ask because you have to make sure your routers Internet Settings are inputted in the DS :O.
If you answered Yes to Step 1
Step 2: Have you placed a Pokemon to sleep in Striaton City? In the Doc's house? Gotta do that and do the whole sleepytime business before you can log onto GTS and really take advantage.
I'll stop there and let you reply.
