yes its because you have to make a .bat file with a command defined based on the ones shown on the site such as these:

(these are on the link I gave you but its what I use as reference.)
It might be a bit hard to explain this as a friend had to point out the correct way of doing it (the puting them in a .bat thing) but I have successfully ported from UT3 now so I do have an idea what you need to do.
Whats shown on the window that disappears really quickly is the supported games and file formats (I printscreened it to look :P)
Edit: If you do figure this out make sure to not put the exe in a folder where you would have to put a space in the directory its searching in as it will not work (I found this out earlier as putting “unreal tournament 3” means it looks for “tournament” in the directory/unreal folder (which doesn’t exist).
What I do is place it inside the game folder so for you it would be in the “Bioshock” (or is it “Bio Shock”) folder then you do the path in from there to the file you want (though I don’t know what engine version and therefore what format bioshock uses). Then it will dump the extracted files in a folder named what the file was in the same folder as the extractor exe. Also make sure to put the SDL.dll with the .exe or it wont run.
(I have to say you picked a good time to ask as I only figured all this out properly yesterday lol, though I did manage extracte things last week without having much clue what I was doing :P).
