DSP 4086 Tuning Software Crashing/Not Responding

If your DSP Tuning Software is not responding properly or is crashing, it is likely because the proper USB driver has not yet been installed.  There is an easy fix for this, and it does not require you to uninstall anything.

 
  1. If the tuning software is open, close it.
  2. Go back to your software install files and double-click on “USB Driver”.

NOTE: Make sure to allow it to make changes to your computer if your anti-virus software requests it.
