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?
Welcome to iMore. There is a very good chance that the file you are trying to open is from a newer version of AI or that the file is corrupt. In either case there is not much you can do. You will either have to find a file to fit your version or recreate the file. Sorry I could not offer you better news.
