Seems I missed (lost) a Secret Key Change

I had used earlier versions of 1Password and persisted as changes and upgrades were made by developer team. With the release of Catalina I decided to take advantage of the newest goodies and features. I signed up for a one month free trial. I will admit I didn’t fully read “instructions” — I was interested in trying out the new interface etc. In fact, when a string of characters (Secret Key) showed up in a window I didn’t fully associate with 1Password, I was thinking scam or something else. I saved the string of characters (in 1Password!). I never remember doing anything with a Secret Key in the first few days of using Catalina. Everything seemed to work - full access to menus, it was NOT Read Only.

A few days ago after some Catalina problems that forced me to reset my AppleID; I discovered that 1Password’s interface was limited — I could sign in via the Account menu but most other menus etc were grayed out. This is where the real problem began. By this time I had a vague sense of what Secret Keys were for. So, I got the only Secret Key I ever got (or was able to find) and tried it in the login dialog. The response was [Your email address or Secret Key are Incorrect. Your Secret Key should start with A3-TSVM8A]. The Key I stored away for safekeeping began with A3-VMD2T2.

I have tried searching my computer for a Secret Key beginning with A3-TSVM8A to no avail. So I guess I need some assistance. My 1Password Password is OK, my email address is OK but I need a valid Secret Key to proceed, get logged in and begin to get efficient at using this fine product
