Hello all!!

I'm trying to create a first "Hello World" programm for my ds. The code is very simple:

SCREEN_TOP = 1
BGTopText = Screen.LoadTextBG()
Screen.Initialize( SCREEN_TOP, BGTopText )
BGTopText:PrintXY( 10, 12, "Hello World!" )
DSLua.WaitForAnyKey()

But the emulator nogba says the following:
Secure area below 4000h, cartridge won't work on real NDS

And that's my problem is doesn't work on my DS.

Is it something about configuration? I tried version 0.5 to 0.7 of DSLua.
Would appreciate little help.
Greetings,
Tom
