Followed the video twice, and totally reinstalled, but still not sure what I’m doing wrong.
I can get the crosshair to come up on screen, but it’s no where near the centre. It’s sitting up the top right hand side of the screen, about 2 inches down from the corner and 1 inch to the left.
Is there some other setting that was left out of the video? I’ve gone over the settings like 15 times, and I’ve done it completely right as far as I can see.
I used the guide written in this Reddit thread.
I watched the video and I noticed four lines differing.
Try those instead.
Good luck! 
You can also just wait a bit and try the new crosshair option SD will implement in DB later. I’m not sure if those will be live next update, but I guess there’s a good chance to see them implemented.
Yeah sorry forgot to post. Got this sorted. Someone suggested I needed to have playclaw closed while editing the txt file, and that worked.
When it was open every time you closed the txt file after saving it, it just reverted everything back to default.
