I forgot my maplestory pic!!

I first played maplestory many years ago, and quit just after they introduced that 2nd pin thing. but now i want to play again i can't rmb what pin i used.

The thing is...i also forgot my asiasoft id and pw. and i forgot what email i linked to the asiasoft acc so i can't send myself the information. the only thing i rmb is the maplestory id and pw really. so is there any way that i can either retrieve my asiasoft acc if i've forgotten everything, or bypass the pic?

and my friend who quit about the same time as me was prompted to make a new pic, instead of using her old one. why is that?
