Where did you get the SKP file? Is it one you created?

I have on a couple of occasions created SKP models of tiny bits of hardware that have some issue with geometry that SketchUp didn't like when it saved at close. I couldn't get them to open again without an immediate bugsplat. I discovered that if I e-mailed the file to myself, I could download it and open it successfully. After repairing the bad geometry all was fine. Why that worked I can't say but it did work.
