Hi Smelton
I'm reffering to the license file that cnc drive send you when you purchase the the uccnc software. I'm not sure but I think you have to pay a bit extra over the cost of the hardware. I got mine on a special offer a while ago, but uccnc is pretty cheap considering how good it is. (it got my cnc machine working in no time at all after idly sitting around in my workshop gathering dust for years because I couldn't figure out the software that came with my machine)
Cheers
Andrew
