DDJ 1000 "Drivers Not Recognised"

Hi,

Since updating to the new drivers for the DDJ1000 and Mac OS, my DDJ1000 is now no longer recognisable by my Mac. I've tried re-installing the drivers multiple times, however it is blocked from progressing, as my DDJ-1000 is not recognised. 

Having dug around forums, and trying to fix for last hour, I believe I may have overwritten the last driver, rather than uninstalling it? Unfortunately I'm now stuck and not sure how to move forward.
