Pro Micro - 5V/16MHz Non Sync

I have the Micro Pro- 5V/16MHz with ATMega32U4.

I am trying to upload a Sketch.

I always get “avrdude: stk500_getsync(): not in sync: resp=0x00”

I followed the installation guide on the website. I installed the driver and Hardware file. My computer sees the board and has assigned a port to it, which is good. I’m using the Arduino programmer from their website. I select the Sparkfun Micro Pro 5v/16MHz option with the assigned port on my computer. After verifying and compiling the sketch I tried to upload load to the micro pro. The yellow LED starts to blink but then alternates between the green and yellow LED on the board. Then I get “avrdude: stk500_getsync(): not in sync: resp=0x00” Does anyonehave an idea of what I’m doing wrong. By the way, now everytime I connect the Micro Pro to my computer the LED will alternate between the green and yellow LED.

Any bit of help would be much appreciated. Thanks
