Adobe Illustrator file format is having difficulties

When I tried to open the .ai file in Adobe Illustrator 10, it displayed an error which states, " Adobe Illustrator file format is having difficulties "

What should I do for the problem?

There may be a TMP file in the same folder, you can try renaming it to AI and see if this opens. Helped me on a couple of occasions but also has not worked in the past. If it useless, there is a good program: Illustrator Fix Toolbox https://www.fixtoolbox.com/illustratorfix.html

drumdrum - can you send me the Illustrator file ? 
Those tools as you mentioned Ignacia are not worth attempting to use.
