I message on imac not working. recently had a logic board replacement
Hi my imac recently (2days back) had a logic board n a video card replacement. ans suddenly my imessage is not working, when i go to accounts n try signing in, it shows "The server encountered an error processing registration. Please try again later." i only use imessage, not any other like gtalk n all that. I tried many things but dint work so, HELP please! oh yeah n my imessage was working yesterday, when it came from apple care after the replacement, but then i updated it from 10.8.2 to i think 10.8.3 n imessage stopped working.
Thanks
