Please this come up whenever I open a file

Please how can I understand what this means. whenever I open a File after like 2 hours, when i want save my work, i will get this notification, i do not understand?.

Do you have the file stored on some kind of server?

Thanks Georg, Yes in Creative Cloud

Georg, Could that be the Problem? Thanks

Most likely. Try to put the file on the desktop and see if that stops the message.

ok Thanks, i will try that immediately,
