Can't install after changing from US to Canadian version

Question

I had a paid up-to-date membership to the US Mac Q Deluxe.  When I tried to update I got a "have to renew" dialogue. Support suggested changing to CDN version, since I'm in Canada.  They cancelled the US one and started a Canadian one.  Now when I try to open Q I get hung on "verifying membership status"  I have uninstalled and downloaded a new one from the CDN page.  Still hung at membership stage.  Could this be because I am running High Sierra?  Not supported but should be able to still use it. No?  And what does that have to do with membership status.  Thanks.

Possibly, yes. Others are having that same issue with High Sierra & Mojave. They are supposed to work but there seems to be a problem with getting logged in the first time.
