'Unexpected file format'

It’s another one of those ‘unexpected file format’ problems. I’ve read through a few posts and it seems some file can be recovered. Fingers crossed this one can be too (see attached dropbox link). My file crashed whilst saving so it left me with a .tmp file and a .skb file. The .tmp file is small in size and doesn’t open (tried changing to .skp file and that doesn’t help) The .skb file is the same, converted to .skp file and that too produces the same ‘unexpected file format’ message.

I’ve worked with varying sizes of models for years now on sketchup and never come across this. Some people say it could be to do with extensions but again I’ve used the same for a while.

If anyone could help recover it I’d be very grateful.

Thanks in advance

Mike
