okay, got pokemon black last sunday and figured out i needed to do an update of my AR for my DSI before i could use any codes(the need for the update is because it froze when i pressed 'boot games with codes'). i went to the codejunkies site press AR2010.ENG.firmware.1.25.14 at the bottom so i could download it but when i pressed another button to unzip it it said that my adobe could not open it and i now have find something FREE to open it, but can't find anything. Please, please help, i'm about to pull my hair out right now.
