If you see anything other than success, then you need to update or install the correct version.
2. Go through the setup process again, to ensure everything is set correctly

3. Plug the device in. Does it have a blue glow to it, and when you press your finger on it you see it turn red for a few seconds?

If not, then there is an issue with the device itself or the port it’s plugged into.

If you still have issues, then it is something specific with your machine, permissions or setup. We have technical team that can quote to call in and remotely help you review the issue and provide a solution. Please note there will be a charge for this.
