Sage Installation

Greetings,

I've been using Sage for a couple of years but am now unable to activate the 2022.3 update with my Accunt ID, which isn't recognized. Sage support is AWOL (can't get through to any of their support numbers and they didn't call me back), and I need to get this up and running to do the CRA remittance math. When I login to the online account, there are no account or activation or serial numbers showing.

Any suggestions?

Really, really fed up with Sage now.
