nds problems after the roms start

I resently downloaded 1992 - Assassins Creed Altairs Chronicles (U)(Micronauts).nds, only problem is when i load the ROM and pick the language it says that the no$gba cannot read data. Turn power off and reinsert the game card. What am i doing wrong? i fallowed all the instructions but what is it trying to read? and if it can't read it than is it perhaps corrupt? :'(

Make sure you use No$GBA 2.6a and No$Zoomer.
You can find the links here:

Thank you works fine now! :D
