I was notified that the new Circuit Studio v1.5 is available by launching Circuit Studio then selecting View / Start and making the appropriate selections.
But when I select View / Start I get an Altium home page with a big 404 Error indication, and a "Footprint Not Found, Sorry, it appears the page you are looking for doesn't exist anymore or might have been removed" message.
I tried configuring my Circuit Studio to check for updates "on start up" and it took me to the same page.
So how do I upgrade to the new v1.5?
