I am looking in the right folder. And I first noticed the problem when running Poser and discovered all my folders empty except for the new prop, so I'm certain I'm in the correct folder. I don't know why this happened! Dropping a Textures folder (for example) into my Runtime folder should only replace a texture of the same name if there is one. It should not replace the Textures folder with the new folder. Right? But this time it did. And with all my Runtime folders. If anybody can restore my folders, I will even pay you. Please. I'm very desperate here. I can't have lost everything.
