V/V error

[#1]

Hi, my Illustrator is in Czech, so I'm not sure if the error message is similar in English, however when I try to save my adjusted PDF file, error message "V/V error of the file" appears and the file is not safed. It happend just now, before that I adjusted and saved 5 other files with no problem.

Restart of computer/Illustrator didn't help.

Thank you in advance for your help.

Which version?

Which system?

Where do you save files?

When was the last computer reboot?
