I have several thumbnails that are not working on mine also. On a few someone must of made the png file wrong. shrugs If you get Yarps P3d0 you can fix this by making rsr files from the png's that are there - delete those pngs and then poser will make its own png files from the rsr file your made. Or wait till they send a fix. I am to nosey to wait, I want to see everything without having to click on it. :-)
