I have retired from designing so have not updated my programs for awhile.
I started a new project today for a family member. The are some colors and materials that seem to be the default set.
I would like to change the colors and materials, but the library is locked.
The list of materials is there with thumbnail samples, but there is a little lock symbol on each one. So I can't use it in my project.
Also, there is nothing in my 'My Library' folder.
