Hacking DSTT and DSi problem

[NDStemp]

Okay so my sister just found her DSi but her DSTTi doesn't work. The firmware on her DSi is "1.4.1U".
Everytime she tries to open up the "Star Wars" icon which is DSTT, an error occurs and it says:

"An error has occurred. Press and hold the Power Button to turn the system off. Please see the Nintendo DSi Operations Manual for help troubleshooting."

Any help is appreciated. Is it because of this new DSi update I hear that blocks DSTTi from working?

I get a white screen upon running the .nds file for that.
