There is no official public documentation of that error message as far as I know, but according to reports, it can mean (at least sometimes) that the same Apple ID is being used with the iTunes Store or one of the other Apple content stores, and the payment method is invalid. Sign in to the store and review your account. You do not, of course, have to provide any billing information to set up an account to use only with iMessage, as it's a free service.
Otherwise, do what the error message tells you to do.
Thanks for trying to help Linc!
Unfortunately it did not solve the problem. I change payment credit card, and even modified the password of my Apple ID. Still unable to make iMessage come back to life...
I got this from Console:

Any other idea to solve the problem?
Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.
I ran step 1 and it worked, so the issue maybe be with a file within my user account?
I was unable to test in safe mode as I was unable to get my system to start in safe mode. Not sure what I was doing wrong. I did not hear any system beep after powering on, but I pressed the shift key twice as instructed and it logged me in normally.
Back again! I tried step 2. I could run safe mode, tried iMessage and same problem popped up.
As a summary, the problem is there in both steps. No matter I enter as guest or in safe mode, iMessage shows same message after I type my password...
Any idea about how to fix this? It's driving me a little crazy...
Thanks for your help.
This could be a complicated problem to solve, as there are many possible causes for it. Test after taking each of the following steps that you haven't already tried. Back up all data before making any changes.
Before proceeding, test on another network, if possible. That could be a public Wi-Fi hotspot, if your computer is portable, or a cellular network if you have a mobile device that can share its Internet connection. If you find that iMessage works on the other network, the problem is in your network or at your ISP, not in your computer.
Sign out of iMessage on all your Apple devices. Log out and log back in. Try again to sign in.
Restart your router and your broadband device, if they're separate. You may have to skip this step if you don't control those devices.
