R8 motor winder suddenly not working

<p>I bought my R8 and motor winder new in the late 1990s and neither of these objects has been impacted by anything, including adverse temperatures and drops. I have used the motor winder on it regularly, but suddenly I cannot get it to recognize even newly opened batteries. I just cleaned all the contacts on the motor winder and the R8 with rubbing alcohol, but this has not effected a cure. I need it for a shoot tomorrow. Can anybody help me with this today?<br>
