.ai file error
 

Hello,
It has the following problems, today I was not able to open the file in Adobe Illustrator 19.0 application gives the following error: "The file is damaged and could not be repaired."
How to open the image without loss of data in the file?

Probably you're out of luck and need to load a backup. AI has a pretty decent function to detect and repair file corruption - if that doesn't work...

You can try use some alternative product like Scribus but don't get your hopes up to high.

That sounds bad. Try to see if you can open it in another program that will open or import .ai files. Photoshop will do this, as will some 3d programs like Maya.

But as fassy said: don't get your hopes up.
