@haidy_easyeda Thank you for your reply. It happened several times after working on a PCB for few hours. I have reinstalled the program, running it as administrator, and the problem seems to be gone. I have also turned on the autosave function to save every 5 minutes so I will not lose several hours of work again. If the error message appears again, I will contact you.
