It's probably impossible to say without some Wine debugs. I suggest submitting a bug to Wine Bugzilla (http://bugs.winehq.org/) and attaching a log of the program started with 'WINEDEBUG=+seh,+relay,+tid'. It also wouldn't hurt to create an AppDB (http://appdb.winehq.org/)page for MyTrader2009 (or whatever the program's properly called).
