Arduino Due Red light always LIT -is chip FRIED? Help!

Hi I am newbie using DUE board and something has happened to Blink Led ( red-orange) . I will not respond to blink program and continues ON. Is the chip fried or is recovery possible? Thanks to anyone that has ans.

Unfroze red light on Due by installing BlinkWithoutDelay program using Arduino 1.5.5-r2 however I can NOT get Atmel Studio to run same program( BlinkWithoutDelay) . Upload in Atmel Studio is NOT possible! Can anyone instruct me as to how to get Atmel Stusio 6.1 to RUN a sketch.I can see sketch and open the serial window and BUILD succeeds but program will not run and produce output toSerial window!
