How can I make Limewire use its own integrated player instead of Windows Media Player?

[That Girl]

I have two questions. I just downloaded the old version of Limewire (4.18 or something, because I hate the new version), and I downloaded songs, but when I try to play them, Limewire doesn't play them on its own little player like it used to, now every time I click on a song a little Windows Media Player thing pops up and plays the song, which is really annoying because I have to wait for Windows Media Player in all its slowness! How do I make it go back to using the integrated player? Also, when I try to drag & drop the Limewire files into iTunes, it doesn't work. iTunes is the newest version, I just downloaded it as well. Any ideas?
