internal error after reuploading the model. why?

[Asdas]

Hi,

I uploaded a model and it got accepted and went live on Google Earth. And after a short while the imagery changed and the model was misaligned. So I corrected the position of the model and reuploaded it. And I got this message:

We're having a problem with the model you submitted

Unfortunately, we've run into a problem while trying to process this model for Google Earth's 3D Buildings layer:

Internal 3D Warehouse error. The model you submitted experienced an error while it was being processed. Unfortunately, your model cannot be included in Google Earth. If your model wasn't built using the latest version of Google SketchUp, we suggest downloading it and trying that instead.

We would be happy to re-consider any corrected models you'd like to submit. Thanks very much for your ongoing contribution to the worldwide geo-modeling effort. We look forward to seeing more of your models soon.

This is the model: http://sketchup.google.com/3dwarehouse/details?mid=15e57db5d95420983a44f4f37c07761

What should I do???

Thanks in advance.
