Help Please! Arduino Mega ADK and GSM fried..IT HURTS ;(

anyone please need because yesterday building project using arduino mega adk arduino gsm shield mounted in it. plan use adaptor power source instead of usb.

the scenario was:
after had plug in adaptor, board got overheated and  unpluged it. know got overheated because smells burning electronics , knew somethings goes wrong. when came investigate if still works, tested adk
by plugging in computer, unfortunately computer unable detect adk despite power on.my gsm doesn't work, tested mounting in arduino uno , had uploaded arduino gsm program built-in in arduino ide.

before bad event, checked web specification of adk , says recommended(7-12v) , limits @ (6-20v). may check on site.

being aware voltage input , having limited resources, used adaptor of creative sbs a300 speaker has following specifications.

input ac 100 - 240 v 50 / 60 hz
out put 11.5v ac 1600 ma

you may check further information.

given information, know fault may not happen again believe did follow requirements in operating microcontrollers.

please give me information had happen, fault, if way fix it, warranty or anything. please consider current location, lived @ philippines. thank giving time reading this. looking forward comments , suggestions. had attached image of .ouch! cannot self seeing unoperational.;(
