Hello, I downloaded one of the examples from the sample gallery (Nashville example from this link: https://www.chiefarchitect.com/products/samples.html) When I open the plan, it seems that the file has lost all the connection with materials, textures, backgrounds, etc. I followed the steps described in this article (https://www.homedesignersoftware.com/support/article/KB-00104/locating-sample-plans.html), but it made no difference. Any ideas how to fix it? Thank you.
