Hacking Luma3ds (an error occurred while loading payload)

[AmeenX]

I've recently upgrader my 4.5 ods to 9.2 and install hombrew channel and menhax.
when i try to launch luma3ds an error appears message saying: an error occurred while loading payload put the launcher at /luma3ds.dat
I made sure to put luma3ds.dat and luma folder on the root of my sd card!
what's wrong!
