--- Comment #7 from Anton Romanov theli.ua@gmail.com --- Didn't feel like opening a new bug for "not able to login" problem, not sure if hijacking this was fine.
If its fine - maybe this should be renamed to "MTGO cannot connect to login server" ? if not then should this just be closed as it definitely does not crash for me on wine master with win7 and dotnet452 installed
