Hi everybody, It seems to me that the problem results from it bug : #17195 (http://bugs.winehq.org/show_bug.cgi?id=17195) For Luke, there are limitations in the existing wine architecture and it's maybe the reason why AC2 and Brotherhood don't launch with the Online mode. Problem, Luke can't work to fix this bug and i don't know if others devs can search to resolv it.
