Hi, Since the Assassin's Creed : Brotherhood, the Ubisoft Game Launcher was updated. It's actually the 0268 version. For Assassin's Creed 2 and Brotherhood, it's possible to connect at the Ubisoft server having indicated my login and password. The problem come from when i must to click on "play" to launch the game on the following window. I have a message told me that the launcher is already launch etc... When i see the error log, there is a problem with "Named Pipes" implemented in wine. This the complete log after the problem : http://pastebin.com/xDqd5k6m I hope that i have explained correctly the problem to have your help.
