Hi Martin, that's too big to send as a file attachment but yes if you can use some file sharing service like Pilou mentions (there's also one from Microsoft call SkyDrive: http://windows.microsoft.com/en-US/skydrive/home) and send me a link that's probably the only way that I'll be able to figure out what's going wrong since it must be having some problem with some particular piece of geometry in there.
