new computer, old keyboard BW Ultimate

ok, so new computer, getting everything set up and running. Win 10 pro. Having trouble getting program installers to load (they keep hanging up) so I'm at least running my old programs (Open Office, etc), still haven't got that ironed out. My Black Widow Ultimate 2016 was working fine until I realized I didn't have my settings (key programs, etc). I tried to install the synapse program and the installers. It too won't load, only this time it's telling me to turn off the synapse (I can't find an instance of it running). NOW my lights are off and the keyboard's playing dead, only the mouse (which is plugged into the side port) is still working. SO somehow its only playing dead. I've tried plugging it into my husbands computer, no life. tried restarts, etc. nothing is working and I'm pulling my hair out.
