Hasn't worked for me, win 8.1 x64, 14.6rc2, I still have one of the cards showing code 43 (5 out of 6 working) what am I doing wrong?

Also, do you run your rig headless, every time I unplug the monitor my teamviewer session shows a black screen, I can't see anything.

Edit: Manually merged the reg file and it seems to have worked this time, now I just need to work out the headless side of it.
