Hi there @alexluciano
First thing first to clarify this for me 
Have you got a licensed version of Kick 1 that was working before or just installed the demo at the time and can get rid of Kick 1 on your machine ?
Deleting the AudioUnitCache as well as from Logic's Plug-ins Manager won't really delete the plug-in itself, it's only cleaning Logic's database cache. When you have uninstalled Kick 1, have you manually removed the AU component plug-in as well as the VST one ?
Those should be located inside these folders on your Mac :
AU : Your_MacOS_HDD/Library/Audio/Plug-Ins/Components
VST : Your_MacOS_HDD//Library/Audio/Plug-Ins/VST
This is the Main MacOS Library, not the user one but also make sure that you don't have any custom install or leftover in your User Library area :
Your_MacOS_HDD/Users/Your_User_Name/Library/Audio/Plug-Ins
If you find anything related to Kick 1 Plug-in in either one of these locations, delete it and reboot your Mac, you can also do an extra AudioUnitCache cleanup afterwards, be sure to follow this procedure :
1- In the Finder, choose Go > Go to Folder from the menu.
2 - Type ~/Library/Caches in the "Go to the folder" field.
3 - Press the Go button
4 - Remove the "com.apple.audiounits.cache" file.
5 - Remove the ~/Library/Caches/AudioUnitCache folder.
There's also a thread about manually uninstalling Kick 2 on the support page, while it's referring to Kick 2, it might be handy to check some locations where leftover files could still reside.
I suggest to check the above, even if you think you've done that already ( it's easy to miss a step ) and if it doesn't solve your issue you can open a support ticket from the top right ( red ) link on the support page.
Hope this helps, don't hesitate to report back here.
Cheers !
