Hello,
It is probably a message from CSE HTML Validator's anti-piracy code (which helps prevent theft), but if you have recently installed PCtools, then that may have caused the CSE HTML Validator message to trigger.
You could try v10 trial and see if it works. In any case, I would recommend upgrading to get the latest features and syntax checking improvements. v9.0 is no longer in development and there will be no more v9.0 updates.
