The screen print melted??? How hig was your temp set and how long were you pressing? Most rhinestones can be adequately attached at around 350 degrees for 7 seconds (avg). Cover the entire design with a teflon sheet to prevent direct contact of the heat press to the screen printed design. Also, it is my understanding that rhinestones may not adhere to all types of ink, so it will be best if you are pressing the stones onto a direct portion of the shirt.
A little more info on exactly what you did may give someone a better chance to answer more directly.
Good luck
