Multiplaying Vista and XP

[Callidan]

Hello everyone

Well...I usually try to figure out problems myself but I am really stuck now and I really hope someone can help me.

I have been trying to play multiplayer with a friend in Europe but we are running into some really weird problems which now seem to worsen. He has Vista and I have XP. Maybe this is the main problem, I don't know but here goes, the story:

At first, we were able to connect to each other fine, him hosting, but only for one game. If we tried restarting or saving and loading a new game, (does not matter which chars we se) I always get kicked from the game. We tried it when I host a game, he cannot see my server on the list. So, every day, we can only play one game and then not for the rest of the day.

Now it has worsened to the point where I get kicked the first time I try to log into the game. We can't play at all now.

We do not use any weird software to help, just the games. We have both tried starting up our computers in Selective Startup but there is no difference, so I can say with reasonabe safety that the software on our computers is not the cause...

Any help would be greatly appreciated...

Thank you in advance

Has one of you installed a patch or mod or fiddled with any game files? As if one of you has then the other need the same files installed. Other than that what method are you using to connect?
