What did you do to make the game appear in the list anyway?
If you cannot play that way then you can try this
www.pvpgn.org it allows you to play WarCraft 3 on-line with other people on "fake" Battle.net servers and you do not need a real CD key for it, I don't think.
I have never tried this but there are people using it, so it must work I guess. For more info and where to get it read the FAQs on that site and for a server list go to Live Servers.
If you need help with it post. Maybe we can help you with it.
