-3180 is not a standard error and not linked to a specific issue in Now Up-to-Date, Now Contact, or Now Server Manager. Since it is happening from all your systems when trying to create a new category, I believe it is a communication error between the local file and the server database. Have you tried restarting the machine the server(s) is running on?
Is it happening from Now Up-to-Date or Now Contact? And, which version of Now Up-to-Date & Contact are you using, under which OS version?
