3DS doesn't detect Acekard 2i

Hello everyone,After putting some new games on the Acekard 2i, it stopped working and my 3DS couldn't detect it anymore. I have also tried to run it on a DS Lite, but the DS Lite froze at the booting screen and so couldn't run the card. I have already tried to format the Micro-SD-card, but nothing changed. I have read that the 3DS could also detect the Acekard when the Micro-SD-card wasn't in it, I've tried that and it didn't work. The 3DS does still not detect it. Luckily I now know that it isn't the Micro-SD-card that caused the problem. I would really like to be helped with this!Thanks in advance,XInos

This acekard is well known to suffer from contact issues http://gbatemp.net/topic/231412-solving-acekard-contact-issues/

Thank you for your answer.I found out that it had nothing to do with this, it was just that my card was bricked. With another R4 I unbricked the card and I can now play again!XInos
