Hi All I've just installed the new Green Lantern game on my kids two DSI's One of them works perfect, in fact immediately after installation. The other DSI comes up with the message ; 'The save data could not be accessed. Please turn the power off and reinsert the Game Card' Both run the exact same firmware/Acekard 2i etc so I'm at a loss!! I've taken out the memory card and Acekard and reinserted both but no joy. I've copied the save game data from the working DSI, but still no joy. It's got to be a simple fix, hasn't it? Can anyone help please? Thanks in advance Post Merge: [time]1309955271[/time] UPDATE: God knows how, but one of our DSI's Acekards (the one that wouldn't run Green Lantern!) had the 1.8.1 firmware. I've put on 1.8.6 and hey presto - Green Lantern's good to go. Sorry about that - as I said, God knows how that's happened as I always update both together (or thought I did!!!!)
