It spent about 5 minutes doing the initial install (updating .NET) and now I get an error: Code: The program SWTFU Launcher.exe has encountered a serious problem and needs to close. We are sorry for the inconvenience. This can be caused by a problem in the program or a deficiency in Wine. You may want to check http://appdb.winehq.org for tips about running this application. If this problem is not present under Windows and has not been reported yet, you can report it at http://bugs.winehq.org. I don't see anything about using Steam and SWTFU, though. Anyone have any ideas to try?
