Sketchup Help is the Best. Maybe Google ruling the Earth will be okay.

Q: What should I do if my model appears "lost" or is stuck somewhere in the review process?

A: While very uncommon, models can become "lost" in the review process. The most common reason for this is that the model didn’t upload correctly to the 3D Warehouse. One method of determining if your model is "lost" is to try downloading a KMZ file from the model’s detail page. If there isn’t a KMZ option available from the Download menu, then you should remove the model and re-upload it to the 3D Warehouse.
