I recently bought a .Mac accoutn and set the email up to work with Mail.

This went smoothly and was running fine however this morning I got prompted to enter the password for the .MAc account and when I did and clicked return it just asked again.

I then quit and restarted Mail and tried to check email but got the message that there was a problem with the server and I couldnt connect.

Does this mean that the server had a problem for a few hours or is there a problem with my settings?
The Mail was working fine and I didnt change and settings before this happened.
