Can´t open skp file please help!

Hi, I can´t open a file I´ve been working on. I saved it properly, the software didn´t crash. It doesn´t have trouble opening any other file, just this one. Trying to open it gives me a blank screen and not responding message. Anyone?

Upload your SKP file to see if anyone can open it, or maybe @colin can rescue at least the components from it, if not the whole model. He can sometimes perform magic with tools the rest of us don’t have!

The never opening and not responding symptom is different to the usual immediate error message. But still, looking at the file might show up something.
