I just recently found my old card lying around in my cabinet and decided to try and start playing it again, but I'm having problems. I just formatted it with the recommended Panasonic formatter, doing the full format on a 2GB Micro SD. I got the latest firmware, 1.51b, which works with the latest DSi update. I put my Games folder with the games I wanted in the root directory. I started up my DSi, pressed the game icon to turn on the R4i, and I keep getting this error message; "An error has occured. Press and hold the power button to turn the system off. Please see the Nintendo DSi Operations Manual for help troubleshooting." I've tried putting alcohol on the contacts in my 2 year old DSi, and my 2(approx) year old R4i Card, and nothing has helped.
