Sorry. I severely edited my post after realizing you obviously don't have a N3DS, otherwise you wouldn't be in this thread. So don't mind that. I suggest the following:
-Start Over
-Read my post again
-Download the starter kit, extract to your SD card, overwriting.
-Delete the hblauncher folder on your SD card
-Download the homebrew launcher 1.3, extract to SD card
-GO to the first post of this thread and download and extract the payload with the 'E' at the end, if your console is European region
OR go to
http://smealum.github.io/3ds/#otherapp, enter OLD 11 2 0 35 E (again, if you're console's region is European)
-Then try to boot up homebrew launcher
You extract the contents to your SD card, overwriting them.
