Coastal Explorer 3.1 - Installation on 3rd PC - Error saying already installed on 3 PCs

Have Coastal Explorer installed on 2 PCs and trying to install on a 3rd Machine. Getting an error saying already installed on 3 PCs.

The 2 PC we have it installed are

  1. DT-2UA7401N08
  2. LT-8NI8CRPA

I’ve had similar problems when I’ve had to reinstall on a reformatted computer. Call customer support and they can reset previous installations.
