Does SketchUp crash or generate an error on launch?
Launches fine, without errors then freezes and does not respond on save every time. Fixed by disabling OpenGL Hardware Acceleration. Note: been using older sketchup version (v8) for 6 months without this problem before upgrading to 2015 where this issue appeared.
