Thanks for the feedback. I didn't get an email. I had already uninstalled and reinstalled the two plugins via the RLHub before I asked in this forum.
That didn't work. That is why I have now also uninstalled CA4 with all plugins and reinstalled it. I backed up my content beforehand.
Unfortunately, the two plugins are still missing.
When you click Plugins from the Menu Bar in Cartoon Animator 4 it will only show the available Plugins. It won't show the installed Gear Profiles.
So now open up Motion LIVE 2D and you will see the Profiles for Leap Motion, Face3D and Motion Link.
I hope this helps.
