My best suggestion would be to get a motion controller that is well known. I would recommend a UC100 motion controller. I have setup several of them and I personally own and use 2 ESS and 3 UC products. I prefer the UC line.
I would then go with a new cheap windows 7, 8 10 computer and a clean fresh install and setup the machine again from scratch. As Ger21 said, the .062 version seems to be the best one.
