I've recently started having a problem downloading music. I use to click on the lauch button, and the song would automatically goes to my Itunes site. Now all it does, is go to real player. How can I change that format to get back to my Itunes site instead.

You'll need to change the default player back to iTunes. Open your saved folder outside of LW (go to your library, click on Saved Files then Explore...your saved folder opens). Right click on a music file > open with > choose program. Click on iTunes & tick the box to always use the selected program to open files of this type > ok.
That should fix things
