Arduino micro infinite delay

Do I have a brand new arduino micro. My first idea was to make a rubber ducky type device, I got a payload, converted it, and uploaded it. It worked perfectly, but I wanted to make some changes to the delay. I changed it from delay(450) to delay(1000).
I uploaded the code and it didnt run. Reuploaded it, no port has been found. Green led is off. Blue led is on. I tried every way to upload an empty sketch, but I have it set to com 7 and it doesnt show up. The port button is gray. It also kept on changing ports so I dont know what to do.
Thats all.

Upload an innocent sketch like blink. When the IDE reports the memory usage, double tap the reset button; this should invoke the bootloader and allow you to upload.

If upload fails after above, which operating system are you using? What does your operating system think about the board?
