File corrupt due to sudden power loss - 7.07 MB - Need help repairing

“Hi, my computer suddenly shut down due to a power outage while working on a model. Now I am getting the ‘This does not appear to be a SketchUp model’ error. The file size is 7.07 MB, which means the data is inside, but the header is corrupted. I have already tried changing it to .zip and checking the %temp% folder, but nothing worked. Can someone please help me repair this file? Thank you!”

Maybe we can but you have to share the file.

What version of SketchUp are you REALLY using? There is no Free web 2017. Is it actually a cracked version of SketchUp for Desktop?
