Hey there @ghostgolem
I have moved your post to a new topic in the "Technical Support" category, please don't use older existing topic on the forums, especially when it comes to technical issues with Plug-ins, it really doesn't make it easy for follow up, thank you
If you've installed the demo before, try to follow this manual uninstal procedure from the support page, then reboot your computer, make sure to get a fresh Kick 2 download from your user account, unzip the archive and perform a new installation.
You don't need to download any license to authorize Kick 2, authorization is made online by entering your S.A account information. Upon successful authorization, you should see your computer listed under the "My Devices" tab from your S.A account page.
Report back if you're still having issue then, but please specify your system specs like OS type and version + DAW & version that you're using, thank you
