This may seem like common sense, but for those like me who don't know better:
When I double click to launch war2 it gives me an "abort, retry, ignore" error. If you hit ignore it will launch War2. Then you hit M then E to get to Connect screen. At connect screen there is a drop down for server and you can change the server to Moustepher's server.
Sorry if this seems obvious, but I didn't know this drop down existed so wanted to share. Hopefully will get a game in before I crash.
