Cake Pop Dilemma

ok, so for Christmas my friend bought me a cakepop maker so i thought i'd give it a go. the cakes came out perfect but then i had some difficulties decorating them and getting the sticks to stay.
I think i know the problem with the sticks, i was using candy melts instead of chocolate to hold them ... ooppss well we all learn!

But i still don't know why ny icing wouldnt stay. i made it really thick but everything just went wrong  :(

also i dont know how to keep them upright while.they dry.

if anyone has any tips please comment and let me know, would be so grateful :)
