I had my R4 (V2.10T) inserted on my DSi (vs 1.4.1U, haven't updated since I got the R4) virtually since I've got it (around march last year) and it was working just fine. Yesterday, I took it out to put a new game on the SD card and when I inserted the R4 back into the DSi, it flashed the "Meet The Robinsons" icon as it always did, but when I let go of the cartridge it showed that there was no Game Card inserted, and that keeps showing when I insert the R4, even if I press it against the console. Could it be a contact problem? And if so, how can I fix it?
