Replacement Program for NC Studio

Hello. I am glad to find this forum! My name is Randy.
I bought a mill from China several years ago without knowing how to run one. It has not worked out well. I have had a lot of trouble with the controller, NC Studio.
I have three servo-drives, not stepper motors. It has a hand control with it. The spindle is rated up to 28000 RPM. It has a tool touch-off, but I have never used it. It is a manual tool change.
I have come to the decision to try to just upgrade the machine to a more user friendly, and widely used program. I am here to ask for suggestions.
I would also like advice on what I would have to do to make the conversion. I know I am a newby here and I readily admit I do not know what I am doing, so any advice will be greatly appreciated. I am just tired of stressing over a machine that I cannot use.
Thank you in advance.
Randy
