won't launch completed files in iTunes?

Since i upgraded to Limewire 8.2, it seems like all my downloads are opening in Quicktime rather than iTunes (which is my default audio player/defualt internet sound player). To get them to open in iTunes, i have to navigate to them from iTunes and convert them, a pain. I used to just be able to launch from Limewire and have it go automatically into iTunes. i can't find any preference setting for this in Limewire. Is it just that I'm suddenly getting a bunch of mpeg-only downloads that have to be converted, or is there some setting i can change? Also, Limewire often makes me click through it's configuration screens every time i launch. Whas up? In general, this version has been more buggy for me. Am in OS 9.2.
