I make a lot of work, i saved it many times. i was working offline (no internet connection)
Yesterday, i finished my work, i saved all, and after i manipulted the design toi see it on many angles,
and application crashed. After that i can not open anymore this file. I make work on a mac, i try open the file from my pc, but same problem.
When i connected my mac to the net, it has updated the version of the file to the cloud.
now the cloud version is corrupt too.
I have apened an older version, and it is ok, but all my last work is missing.
When i want to open the last version (with all my work, version 29) application close, with error message, file corrupt.
is it possible to repair the file ?
i have a week of work on it.
To prevent loose of work, i save regulary my file, but when the file is corrupt, what can i do ?
Can you help me ?
