I am on Win 10 and have installed Camtasia 2018.0.7 (Build 4045). It is a new install. My Library in Camtasia left panel is empty, no default items. Camtasia 2018.libzip is present in C:\ProgramData\TechSmith\Camtasia Studio 18\Library 4.0 folder as are my Custom libraries. When trying to open .libzip package (2018, the latest from your website, or version 9), the install fails with "Unable to import selected library" message. Essentially, I cannot use any assets that I download. I cannot install assets v9 and convert them to 2018 libzip either. Is there anything I should try to get the menu items visible.
