Sicko

Well now guys I seem to be experiencing certain difficulties. First of all I have an original (AUS) copy of Pokemon black and I have myself an; Action Replay DS "EZ". (oh and Yes I see it says 'US only' but I have been able to use US codes with my AUS copy's in the past) -My problem is that I've entered this code, checked it over probably about 8 times in less than 2mins (making sure I haven't gone blind yet =P) , all seems correct and yet it still doesn't work..it seems to freeze after I press 'Start', it shows me what I call 'the white screen of death' (I have waited 5-10mins to see if it loads but nothing happens)..any help please? T.T Edit: Problem all fixed after countless hours surfing the web for a solution, now there's a new problem, when I click on Meoletta's 'Summery' in game it says; 'An error has occurred, please turn off your console' -or something along those lines and the game freezes with a blue screen..any help with this please?
