make: *** [initialload-upload] Error 1

This is the error I get at the end of the make command. My COM Port is COM 2. I am running Windows 10 Baud Rate doesn't seem to matter as I have tried 112500 and 9600 and both come out with the same issue. I am able to see programming mode on the screen as it seems the initial program loaded onto the chip shows, however the scrolling line 2 is not scrolling (I gather this is programming mode). ANy clues on where to go to from here?

As a guess, I would say there is a compatibility conflict between the ftdi cable and windows 10.
