Lost file

[ferrcorni]

Hello there...
My windows OS recently had some flaws, took it to the shop and the hard disk had to be reformatted (ouch). My hard disk had two partitions; 50gb for the OS and program files and 250 for storage. The nut cake at the shop over saw this and simply reformatted the entire disk. I recovered some important SU files after he reinstalled windows again but they won't open. They have the correct file extension, date, and file size---but just won't open. I get a "doesn't seem to be a sketchup model" message when I try. Has this ever happened to anyone and is there a way to correct the file? Please help!!!!!!!

Most likely that's file is damage,no help in that case.
