Given error when trying to register for FaceTime

I'm trying to set up FaceTime. I entered my apple ID and password and kept getting this message: The server encountered an error processing registration. Please try again later.

I'm not sure why or what's going on. I just email Apple but not sure when I'll get a response. Anyone else having or had trouble as well?

My computer software is all up to date.

I want to get this working asap. Thank you.
