acekard 2i cards won't work every time they are inserted into some ds lite's, but will work in other dslite's. My son has a new lite and so do I and sometimes you have to reinsert the card or restart the lite many times before it will be recognized and on the first try it will work in my lite. My acekard 2i card will work every time it is tried in his lite. We have had his acekard card since May is this going to happen to all the cards once they get a few months old? For the past few months it has worked flawlessly on his lite.
