I don't know if you have searched these, but use the string "skp, skb, unexpected file format" in the Google search box and see if the top three topics have any insight for you. There was something in the third topic that may work.

thanks!

Hi everyone, I am sure some people must have come across this problem before.. and I have read many posts about this error...
I couldnt open my original Sketchupfile or any backup files (.skb and .skp).. the "unexpected file format" message keeps popping out...
Is there a way that I can recover the files???? I have spent ages on it
Or can I upload it somewhere for you guys to try opening it for me?
Thanks a lot!!!
