Today, while I was working in AI v25.4.2, I got the dreaded "unknown error has occurred" message. Having been through numerous gyrations to get *that* version running smoothly, I decided to uninstall and re-install it. Same error. So I uninstalled that version, and installed v 26.0.3, resetting workspace and preferences. I got a file open, made one small change, and on trying to save, got the same error—Again!
There are no weird characters in my file names, I have a printer on and running, Save in Background is turned off—all of which have been suggested before. I am at wit's end, and under a deadline. Does anyone have any ideas? I am willing to try everything at this point!

Thanks in advance.
