iMessage

iMessage has stopped working & is asking me to set it up.

I put in my ID & correct password, make it to the next screen & chose my method of notification. Then is states verifying & right after that I go back to the original sign in screen again.

I am stuck in some "loop"? It started about 2 weeks ago.

I have reset my password etc. & it does THE SAME THING!!!

HELP ;).
