Maybe a corrupt terrain file? It's Mesaview right now, you may give it a try and delete it from your ahiiterrain folder
just tried that, and nothing. still the same effects.
Was AH trying to download the map?
Sounds like some ports being blocked. Could be your firewall, or router firewall, or ISP. ISP's have been known to block some ports used for various nefarious activities. They never let you know about it though.
whats the easiest way to find if their being blocked?
