Can't sign in on iMessage and FaceTime after upgrading to ML

I am still having this issue. Any other ways to fix it?

Hi i got a problem with my imessage and facetime

Whenever i login it says that "u wer signed out of imesage because ur apple id or password changed" but im fact i can use my apple ID in app store. Whats wrong???!!:(

PLEASE HELP!

Hi search-4-help,

The Duplicate (but not logged in Second (or third) iMessages account, can be delete the following way:-

With the Finder as the Front app ( in the Menu bar) go to the Go Menu

Hold down the ALT key to see the Library option

Select the Library and then open Preferences.

Find the file

com.apple.imservice.iMessage.plist

Drag this to the Trash.

Restart Messages.

You may have to re-enter you Apple ID

I don't know if ths will help with Apple accounts that don't use old mac.com email addresses but it fixed my problem:

Go to Messages preferences and click "Accounts" tab

Select the problem account and then, in the "You can be reached for messages at:" box, click the "+" button.

Enter the email account you want to use (doesn't have to be your Apple ID email) and hit "Return".

You should then be asked to enter your Apple ID password to validate the email account.

Messages started working immediately for me after that.

Still have the same problem, nothings worked!! please help

I also still have this problem and none of the options presented here have worked. Any new developments?

I'm having a similar problem, but have an additional detail, which may help someone else decode what's happening.

I have a late 2011 MBP 8,2 running OSX 10.8.2

I use two different user accounts on this machine. <--- the difference!

One one user account, iMessage authenticates as expected and works fine.

On the other user account, I'm seeing the same message being discussed:

"The server encountered an error processing registration. Please try again later."

What to do, what to do?

Same problem, upgaded to ML today and came across this problem. Seems so stupid, no reason why it won't work.

same problem here 😟

apple please

HI,

In iTunes (I know, bare with me) go you your Account settings.

Bottom left is a Contact Support option.

This launches a web page.

Again lower Left is a Contact Support.

After that it gives you options of real contact with a real human being.

Ask the iTunes Support to sort your Apple ID.

Where is "account settings"? I went to "manage my account" but don't see a "contact support" option nor do I see an "account settings" area anywhere else in Itunes. I also checked preferences.

HI,

My fault, I should have been more specific about starting at th iTunes Store bit first.
