Sketchup 2016 Model Upload Error

Hello,

Have been consistently getting errors uploading models from SketchUp 2016 into Sketch Fab. Dont think its a file size issue since its well under the 200MB Pro limit. Tried both SketchUp direct upload and also uploading as Collada files directly from the website. Please help - urgently need this for a college application. Thanks.
