First of all, you should always try the latest version of Wine first. This currently is wine-1.1.29. There's also a bug report about Battle.net not working in Bugzilla (found that by searching for Frozen Throne): http://bugs.winehq.org/show_bug.cgi?id=9787 And there is a full guide about how to make it work in the AppDB: http://appdb.winehq.org/objectManager.php?sClass=version&iId=3126 I hope that this helps.
