Razer Naga question

Hey all, I have an old razer naga from a few years ago. It has the option to be both wireless (with a charging station) or wired into the computer, as well as the three different 12-button sets on the left for different sized hands. I use the biggest hand size on the left and that is fine, but my 3 toddler baby girls lost my charging station and wireless receiver, AND have ruined my wired cord. I didn’t mind so much losing the two wireless parts, but now that the cord is all twisted too, the pc has trouble receiving info from the mouse. I don’t see any options in the razer store to either buy a new wireless receiver and charger, or the option to just buy a new cord. :-( Can anyone shed some light on this for me? If I HAVE to buy a new mouse I guess I will but I really just need either the cord and/or two wireless parts, and would prefer to get just those, since flipping diapers and formula cost a lot for 4 kids under 5. :-P Thanks! -John
