If you do not have your own licence key, very high probability that it is a dubious copy of Mach3 and all bets are off when it comes to problems.

A friend of mine bought a Chinese machine with a similar Mach3 "licence"; he ignored it, downloaded a genuine copy and bought his own licence (he had taken this into account when pricing the machine), and I assisted him install it, the appropriate plugin for the USB motion controller, and it's all been working very well since. You are going to have to buy a licence, get the genuine version of Mach3, and then look for assistance here to get it all working. Based on my previous experience, this shouldn't be a big deal, apart from the extra cost. No showstopper, just a bit of a pain.

Ignore all the nonsense about "reskinning" - out-of-the-box Mach3 (assuming you get the plugin to drive the USB motion controller to work, and I'd be surprised if you can't) will work just fine. There isn't going to be anything exotic in a machine like this that needs much more than Mach3 can supply. Does the USB motion controller have any useful identification markings on it?

As Magicniner has suggested, you also have the possibility of dumping Mach3 and the supplied motion controller; for about 50% more than the price of a new copy of Mach3 you could buy a UC100 motion controller plus UCCNC software plus a cheap break-out board - good pedigree hardware and software. However, personally, my first step would be to download a demo (free) copy of genuine Mach3 and just see if you can get the motion controller plugin running with that.
