Is my smoked ham still good?

I have a hickory smoked Fully cooked boneless Ham that is not sliced in my fridge. The expiration date says use or freeze by June 17, 2011. We bought the ham and opened it April 23rd for Easter Sunday. It's been sitting in the refridgerator wrapped in the plastic after having used probably about half of it. Is it still ok to eat? It isn't sliced, and it's been a little over two weeks, but it is smoked.
