I bought Fat Channel XT. Intend to use it on logic. So downloaded the Presonus Hub. After installing and running the hub, it asked me for my account details, supposedly to authorise my computer. I entered those. Afterwards nothing happened. When I click the "Authorise" button - top right in the hub, NOTHING happens. Just seems stuck. I re-installed it. No go. I'm running Catalina and the Mac operating system is totally up to date. Intel iMac. Hope you can help, or the software is totally useless to me like this!
