I'm out of ideas. There are two bugs already for Entropia not starting: http://bugs.winehq.org/show_bug.cgi?id=14137 http://bugs.winehq.org/show_bug.cgi?id=24943 Neither has had an update in awhile. Take a look at both, pick the one that seems closest to your problem (if you are seeing Wine's crash dialog, it would be the newer one), and update it with a comment that the problem still exists in current Wine.
