blank screen on R4?!

hey
after i have extracted my game and opened it on my R4
the screen just turns white on my ds and it doesn't change .
can someone tell me how i can fix this problem?

have you read the common issues sticky?

Only time that happens to me is when my games get corrupted (which is a rare chance, but it happened many times when I used to pass games from my old pc) Probably just one of your USB ports getting old, which makes transferring slower. If you passed it via USB, put it in another one but if it was from a MicroSD Card reader, try using another one. (if you have a spare around)

Is it when you try to load the game or the actual firmware itself?

its when i try loading the game.

Read the Common Issues then :)
