Hey Benbjj,

  In addition to downloading and install the latest version of GearBox 3.72, you will need to install the Line 6 drivers for your operating system as well:

  Windows Drivers 4.2.4.4:

  Once the drivers are installed you will need to install the Line 6 Monkey application from the links below:

  Windows Line 6 Monkey 1.41:

  MAC Line 6 Monkey 1.41:

  Once Line 6 Monkey is installed, remove any additional unnecessary USB and firmware devices from your computer when troubleshooting this issue. Make sure to connect it directly to a USB port and not a USB hub, extension, or keyboard of any kind, preferably connect it to a USB port on the rear of computer. Try using additional USB cables and every USB port available until you are able to launch Line 6 Monkey and detect the device.

  Once Line 6 Monkey is launched apply any updates that are available until you have a green check next to each component.

  Once all of this software has been installed you may launch GearBox and use it to open the tone files that you downloaded from CustomTone.com.
