I am home and can provide this step-by-step walkthrough of my most recent attempt.
1.) Removed Preferences.cfg from C:\Users...\AppData\Roaming\Ableton\Live 10.1\Preferences to reset Live as per: https://help.ableton.com/hc/en-us/articles/209070609-How-to-reset-Live
2.) Uninstall Kick 2 64 bit via Windows Apps and Programs
3.)Delete Sonic Academy folder from C:\Users...\AppData\Roaming
4.) Start Ableton 10.1 (new default project)
5.) Close Ableton 10.1
6.) Download Kick 2 from https://www.sonicacademy.com/my_account/downloads/plugins
7.) Extract Sonic Academy KICK 2 - V1.1.1 and run KICK 2 v1.1.1 64 bit installer, setting Destination Folder to: C:\Program Files (x86)\VSTPlugins\
8.) Start Ableton 10.1 (new default project), setting VST2 Custom Folder to C:\Program Files (x86)\VSTPlugins\, which locates Kick 2 x64
9.) Load Kick 2 into a new audio track. Registration modal pops up.
10.) Click "Connect to your account..." Enter username and password. Message: This device has already been registered - please revoke any devices at the link below
10a.) Note I can no longer revoke devices as per limitation set by Sonic Academy
11.) Click "Offline Registration, following the 4 steps
11a.) On Step 2, I get the following message from the Offline Registration page: "The form contains 1 error
License registration failed, you aren’t allowed to register additional devices"
12.) I am left with no further alternatives at this point.
