Hello,

Cara Mengatasi Unexpected file format di Flash Cs4 cs5 cs6. Using The Standard Version of SketchUP (not pro) to Export to DXF or STL Format.

I have a project for school to design your own house with garden. So I started working at home, with version 8. Unfortunatly, my school isn't really up-to-date, and have their computers running on version 6. So I can't open my version 8 files on version 6. My solution was to save my project on version 8 as a version 6 file.
I haven't tested that yet at school. But I can't work on it at home anymore, it says 'Unexpected file format'. I googled a lot but couldn't really find someone with the same problem as me.
Does anybody has the solution for me to open it again on version 8?
It doesn't care if I can only work on it on version 8, because most of the time I work at home.

Error Unexpected File Format

I have been working on a small project, as yet unfinished - and when I saved the job, I received a message 'No Error Found'
I then tried to 'save as' a different file name - same message appeared.
Numerous attempts to save ended with the same result,
When next I opened sketchup, I tried to re-load the file and now recieve a 'Unexpected File Format' message.
The file I want to load shows up in Windows Explorer (thumbnail mode) with a small thumbnail OK and a file size of 1216 kB.
I even re-named the .skb file and tried to load that, with no luck what so ever.
Anyone have any ideas or suggestions on how I can recover this
Previously created projects (different jobs) all open okay, as a test of Sketchup itself.
