If the lights do not flash on your Atlantis unit, you will want to make sure you have istalled the USB Drivers correctly.  To do this reference the USB Installation instructions to confirm that your drivers are installed and working in Windows.  If your machine was recently serviced, or if other devices were installed or removed, your driver settings may have changed, or the drivers may not be installed.

If after confirming the proper drivers have been installed you are still experiencing the same problem contact BrainMaster, 440-232-6000, for technical support.
