Yu-Gi-Oh! 5D's World Championship 2010: Reverse of Arcadia language issues

So I have tried all 3 versions, (U,E&J), but every single one is in japanese. Yes I know about the flags. But the thing is that nothing changes, I have tried literally every single flag, and the game is still in japanese. I don't know what else to do, has no one else had this problem?

That shouldn't happen. Try downloading the file again.

Read this thread.

Thanks but, it didn't help. No matter which flag its still in Japanese.
I forgot to mention its a Japanese DSi, but isn't there any way around it? Seems silly that even after choosing a flag it still goes into japanese.
