Hello sperryff56,
Welcome to Apple Support Communities. It sounds like you're having trouble with an iTunes certificate on your Mac. I'd be happy to share information that may help.
Take a look at the steps in this article and give them a try:
If you can't connect to the App Store, iTunes Store, or other Apple services - Apple Support
Also, if you can provide any more information about the issue, like what you were trying to do and the exact text of the message that pops up, that may be helpful.
Take care.
