I'm editing a logo in an .ai file, but when saving it gives an error without explanation. I checked it on different versions of the program - the result is the same. The file is not protected, everything should work. I think it might be a problem with the format or compatibility. Where do they get stable editors for working with vector graphics now?

It's frustrating when changes don't save after editing. One potential cause could be software issues or limitations, especially with free versions. If using a pre-activated version like the Adobe Illustrator download, ensure that it's compatible with your operating system and check for any known bugs. Sometimes, saving under a new name or location can bypass temporary glitches in the software.
