Update takes me to the how to update page not the actual update page

Hi I find this software impossible to update my free lifetime maps. Your site says an update is available, but when I click on update my device it redirects me to the how to update page. If I click on that page I then get redirected to the discussion page. Where do I simply update my device from? it is a Rider 400 with lifetime free maps. I'm running OS-X 10.15.6 & the latest version of your mydrive, & have tried standard & beta versions. My device is connected & routes import ok, but not map updates !
