@russelb923, the only difference in 2013 vs 2015 would be what’s in your session.dat or cookiejar.xml, so deleting those files would clear it, one would think. But 2013 shouldn’t work at all unless you’ve updated your SketchUp.dat per our help instructions, because Google no longer redirects 3dwarehouse requests to us as they did for 3 years after they sold us. Did you do that?
