Hello I'm in Aussie for a holiday and brought my ds and r4 with me. So I get here turn on my ds and scroll down to pheonix wright 2 and click start. It freezes so I turn of my ds. Now when I turn it on all I get is the 'Loading' screen of the R4. I used the micro sd reader on a couple of XP machines and all show it as a removable drive with zero bytes of space and when I click it it says please insert disc. I need help. Thanks in advance.
