Austin English, using Wine from the git repository generates the same error you described in http://bugs.winehq.org/show_bug.cgi?id=35680#c5.
I've deleted my .wine directory before testing.
I've also tried with "./winetricks dotnet20". Again, the same error.
The application needs dotnet20sp2 (it will tell you if you install dotnet20 before running setup). Doing: rm -rf ~/.wine winetricks -q dotnet20sp2 wine FreeStudio.exe
then running starts the application just fine. I was able to convert a video to an mp3, which plays fine in a native player.
