TI F28069M Launchpad external mode Error occurred while executing External Mode MEX-file 'ext_serial_win32_comm'

Hi everyone, I am trying to connect my F28069M launchpad to simulink using the board support package. Here is my setup: Windows 10, Matlab R2015a, CCSV6. I am able to build the code and it is loading it properly to the board because I see LEDs blink, but when it tries to connect to the board I get this error:

Error occurred while executing External Mode MEX-file 'ext_serial_win32_comm': Failed to connect to the target. A time-out occurred while waiting for the first connect response packet. Possible reasons for the time-out: a) The target is not switched on. b) The target is not connected to your host machine. c) The application for the model is not running on the target. You might have clicked the Stop button.

Unable to connect to the 'TI Piccolo F2806x' target

I have read through other posts and my mode is set to external and the time is inf. I have also verified that the SCI_A is set to 115200 and the COM port is loaded and set correctly in the Coder Target menu. Does anyone have any other ideas?
