Age of Empires: Rise of Rome compatibility issue

Hi all,
i'm trying to play multiplayer on this game through a home network. when i create a game i cant find it when i search through another vista running computer it doesn't appear. when i run 2 XP running computers (which are no longer with us), it works fine through those (using a wi-fi connection) and through vista i have tried Wi-fi and ethernet connection, but still no luck. i have minimized the game to unblock the windows firewall for the network accessing, but still no luck. i tried running the game in compatibility mode in both 98/ME and XP and still, again, no luck. i'm out of ideas !

i should probably add that a few months ago i tried running it through 1 XP PC and 1 Vista PC and it didn't work on there either.

i really like this game. can anyone think of anything else?
thanks,
luke

Have you tried "run as administrator" by right clicking the game's exe?

yea, just tried that now. still same problem. s.o.b game...

I got the trial version working with my wifi home network.

1. First make sure both Vista computers detect each other [example]

2. If they do not then enable network discovery and file sharing on both computers [example]

3. Vista should then detect the other computer, if it still doesn't then make sure your network is setup correctly.

On your router, you must DISABLE UPnP. I have try this with a Linksys and D-Link router and it work.

For some unknown reason, UPnP screw this up.

Then, your opponent will be able to see you and join on the multi-player match
