From what I have heard (I won't use the program), the Trial version does not have the option, but it's not supposed to block it either. Try disabling ZoneAlarm and see if you have problems or not. If you still do, then it's something else that is causing the problem. If you don't, then it's ZoneAlarm and you're probably better off getting a better firewall than that one.
