Cannot read data...

I get this problem when trying to start up the game, i have the R4 for my NDS.When i click on the game to load up it seems fine but then it gets into a screen and says cannot read data.I dont know what to do.... any help or is it just that it doesnt run particular games?

Are you using the latest firmware?
