I've read all the comments herein concerning this general area, have tried them all, with no success. I thought if I would be very specific you might be able to help. URL mgc.mlxchange.com will not open. After typing name and password it just spins. I KNOW this site needs Ports 1433 and 80 to be open. I KNOW it is a sequential server. For the life of me can't trigger the right key in ZA to cause it to open. It does NOT trigger ZoneAlarm when I put in name/password so ZA does not log it it appears. Wife needs this MLS system for her real estate business. Can you think of ANYTHING. I may have to go back to free ZA. It opened with the free one. Would prefer to keep ZAPro though. ZA has been non-responsibe to date even with written FAX.
