Am I missing something simple?

[spadekevin]

Hello,

I've been having an issue with the installation of tvpaint on my Mac (which uses the latest verson of High Sierra). From the disc I install the software and remove the dongle as instructed for the driver installation. After I restart the computer and put the dongle back in, it isn't recognised at all despite the green light coming on. I try to open the software but a dialogue box tells me there is no dongle in the USB port. Am I missing something simple?

Please help.

I didn't find the right solution from the internet.
