acekard2i has stopped working

Hi been having trouble with my acekard2i. It was working fine on my dsi,then turned it on and it said please insert card? tried it in a dslite same thing happened... so bought another one and this worked fine for a few days and the same thing has happened again.I don't use the wifi on it so it can't connect to the internet for updates have put and installed the new firmware on it so you go through danny phantom to play the games. any ideas? thanks

I am not an AceKard user but, have you been using the same microSD for both of your Acekards?

Prehaps the inside of the ds has a case of dust-try a gentle blow.Also updates for the card are here.www.acekard.comI never use the wifi updates.

hi yes it was the same sd card

maybe the micro sd card is killing them, try using another one
