iCal notifications

I have received ical notices on some events (by adding @reply tag). When I go to "accept the invitation" to the events, I get an error message saying that the invitation was sent from an email address other than my address. So, they won't show up in my calendar. Earlier this morning, I was able to accept some invitations without any problems. Any suggestions? I'm fairly new to iCal, but I've been able to figure out everything else on my own. Thanks!
