"An error occured while starting the application" Windows 8.1- Arduino 1.0.5 r2

Can any one give me some tips and help on this situation.

Im running a new laptop, with windows 8.1

just downloaded Arduino IDE, and trying to setup Arduino Mega 1560 with firmware sainsmart software for building a 3D printer project just started.

And now the Arduino.exe just start loading and then pop up the message "An error occured while starting the application."

i have uninstall and reinstalled the program 3 times now, and it's still the same message.

Really scratching my head because, driver installed fine, and in fact the program started fine the first time.

then the second came this way.

So any tips, would really be appreciated.

Thanx
