ok, thanks for helping ;DShort story: You can't use FBI on 11.0.0-33. You need to downgrade.
Long story: You need to either find someone who has a custom firmware 3DS to do the DSiWare Downgrade, get a hardmod, sell your current system and get one with 10.7.0-32 or lower, or wait for a 11.0 kernel exploit (good luck with that).
