--- Comment #12 from Joris joris@jorisvanderwel.com --- The original issue was that continuum.exe continuously relaunches itself, before it shows any kind of GUI (it tries to relaunch itself using CreateProcess with a DACL which forbids PROCESS_VM_WRITE). I wrote a patch for wine-staging which implements process & thread DACL's for CreateProcess (these arguments are discarded in regular wine).
If you see the GUI and it the game still does not work properly, there is a different issue. (A common issue for new players is that you have to click on "Profile" to pick a new unqiue "Player Name" and password)
