I have already tried to change a SKB into a SKP or opening SKP directly with SU but this gives the same problem... I have saved my files always but I think the problem is that i had 0 battery and my computer 'glitched' the files..... can I upload the files?

Yes i have set up sketchup to auto-save every 5 minutes but when i locate this file in the documents folder it's a old file from 2014 which i don't need..
Also i have SKB files but here the same problem: unexpected file format!
I've tried to rename the SKB to a SKP but still not working.
Any1 got suggestions!?

Hello guys!

I'm a Belgian architectural student and have been working for 1 week with a model on sketchup.
Never had a problem saving it or restarting it since today!?
unexpected file format is my problem... I've put the files underneath in the attachment!

I realy HOPE someone can help me!
