Hello, I have been using Sketchup for a few yews now to model and render and this is the first time I’ve seen this error. I was using the push pull tool and had a crash, while trying to load back up, I found that both the .skp and .skb had the ‘Unexpected file format’ message when opening. The only thing I can think of that was out of ordinary on that session was that when trying to copy in a paving texture from another job, the control v function didn’t seem to be working. I have uploaded the .skp and .skb in the following dropbox link:
I tried to recover anything useful from both files, but didn’t get much, only some materials.
Thanks for trying Colin
