Comments.Text: it should also be known that the unit beeped successfully and the software let me know the download was finished when I downloaded the firmware to the RCX 2.0

ThreadText: # RCX 2.0 Firmware downloaded successfully but "Run" does nothing
  
  (Asked by: username_0 on 2015-09-20)
  
  I recently was able to install RIS 2.0 for the first time since I just got a 32bit Windows 7 machine.
  
  I got the IR tower to download the firmware to the RCX 2.0 and it showed exactly the same screens the guide showed, but when I got to the point where I test the motors, I found that the "Run" button does nothing.
  
  I tried installing the firmware 3-4 times and still have the same problem, so I'm assuming the RCX itself has a defective Run button.
  
  Does anyone know what's possibly going on? All the other buttons work, they beep and change the screen when pressed, nothing beeps or happens when Run is pressed.
