Got a brand new DS Lite and a new Acekard 2.1 for my son on X-MAS. In a nutshell it worked at first but now the DS Lite will not recognize it. Other DS Lite Game carts work fine. Details... Loaded up the card X-MAS morning and it worked great. X-MAS night he said it was not working. Found out it would not recognize the DS Card. There was a message that said "There is no DS Card inserted", even though the Acekard was present. After removing, blowing in the slow and reinserting for a minute or so, it started working again. Today my son brings it to me again. Same problem. Again - After removing and reinserting several times it was finally recognized again. Things were OK for about an hour when he brought it back and said the unit just stopped in the middle of his game. I turned it off and back on and it did not recognize the Acekard. Played with it again and it finally was recognized. About 2 hours ago he brought it to me again. It will not recognize the Acekard. I took out the Micro SD Card, reformatted it and put everything back. No luck. Now, no matter what I do it will not recognize the Acekard. I don't think it matters but this is the new limited edition Red Mario Edition DS Lite. Did I get a bad Acekard?? Thanks for any guidance or help that can be provided... Also, I did make it clear to my son that he is not to remove the Acekard. I believe he did not touch it.
