I've been trying to download themes from the Theme Shop, and I'm constantly getting error code 004-1045 about 50% of the time. I tried looking up the error code on Nintendo Support, and it said that the system could not connect to the access point, and gave me directions on preventing this problem. I tried connecting my 3DS to my router with the infared literally facing the router's antenna, and I even tried connecting to both my router and my TV's connection, but I couldn't solve this. Any help here? I really need to get my 3DS themes
