I agree with Simon. I received this error and could not solve it. I deleted all unused links from the mysoftware properties in the project menu and then deleted the unused database. he solved my problem. I am sure this will work for you.
Sometimes some corrupted files cause this problem, although you have never used or relied on licensing your software.
