m3 ds real adapter doesnt work

Hello.
I have another question.
I have bought a new m3 adapter for my old nintendo DS and I cant seem to get it to work.
I did everything the instructions said. First format, than download software.
My DS doesnt reconnais the card.
I still had the software from my old m3 card and I tried putting that on it but that doesnt work ether. (And it did work 2 years ago)
I have the same DS and bought the same card as I had 2 years ago so what is the problem.
Do any of you know because I dont know what to do anymore.
Im not really a wiz kid so I dont understand which software works and why... :(
Thanks in advance

I'm guessing it's an original DS? If so, it might just be that the contacts aren't making proper contact. To test that theory, simply hold a piece of paper (that's taller than the cart so you can get it out again) against the label of the cart as you put it in the DS. This should push the cart a little bit towards the contacts. If you don't get what I'm saying (I'm not good at explaining things), then I'll try to give you a diagram.

OMG IT WORKED!!!
Thank you so much..
Ive searched for software and tips online for houres
Who would have guessed that it was so simple..:)
