Have you taken the time to check if it's properly configured or tried contacting Apple Support? For what it's worth, I've had a couple friends who had issues with Messages and it was primarily iCloud related. Aside from a few initial issues when running the beta's, I haven't had an issue with Messages for the last four or five months.
