you need to add the nc50 to the nevo configuration through nevostudio pro.  plug the nc50 into the pc you are programming with via usb cable, then click on the add hardware button. you will probably be prompted to update the firmware. the mac address of the nc50 will be recorded into the program.  you then setup the i.r routing for the nc50, load the file back into the q50 remote, and when the remote reboots, it will ask you to create a zwave network.  should be pretty simple after that, just follow the directions on the remote.
