Hacking Acekard 2i Sticker Removed????

[nomercy]

Before this even happened I put my brand new Acekard 2i into my DSi and it scratched it you can see the scratch marks on the cover I inserted it in to my DSi one again
and the sticker came right off what could be the problem my DSi or the Acekard 2i rubbing up against the inside of the DSi slot???
