Cannot setup 1P7 trial on any platform. Mac app rejecting my assigned key. Am user since 2010.

Here's a step-by-step illustration.

1Password 7 exists as an icon only (see top image).I don't use iCloud, Dropbox, and the manual entry of my Password 6 key failed. My vault is standalone on my old Mac with OS High Sierra. I'm using a brand new MAC with copies of 1 Password6 and 7, neither of which work (see graphic). I can't run the diagnostic because I can't get into the 1Password 7 app.

I received a discount offer for three years, but can't set up an individual trial account because there is a frozen individual account using my email.

I am using 1Password Version 7.9.5 on my iPhone. I don't know if that version is connected to the online frozen account, which may have been set up in 2018 and by support staff because of difficulties I was having with 1Password in 2018. I don't know.
