I just bought a Nintendo DSi and and r4 card that is shiny and purple that says r4isdxc. The DSi asked to update so you can access the download play, so I stupidly said yes. Now I have v1.4.4. The r4 card which was called spiderwick chronicles stopped working. I went to the website on the r4 card and downloaded an RAR file to update the r4 card. Now the card is called Deep Labyrinth. It doesn't work on the DSi or an old DS that we have laying around. It just comes up as a white screen. Can someone help me. There were 2 files when I un-RARed it. I transfered it onto the SD and ran a file. Can someone give me exact instructions on what I should do or how I can get this to work.
