[Wine] [Assassin's Creed : Brotherhood]Online Mode doesn't

[Berillions]

Hi everybody,

I have a problem with this game when i want to play with the Online Mode. (It's possible to play it with the Offline Mode)

The connection at the Ubisoft server works correctly, there isn't the same bug that Assassin's Creed 2 (24590 (http://bugs.winehq.org/show_bug.cgi?id=24590) and 22064 (http://bugs.winehq.org/show_bug.cgi?id=22064).

The problem come from when i click on "Play" ("Joue" In French) ->

The error message says :

Code:
A problem arose during the launch of your game. Check if an other game use the Ubisoft Launcher. If the problem persists, reinstall it



The message in the console :

Which option can i use with WINEDEBUG to find where come from the problem?

Thanks
