Sounds like somehow Musicmatch has become your default player. To change it:
Open your saved folder outside of LW (go to LW's library, click on Saved Files then click Explore). Right click on a file > open with > choose program. Select the player you want & tick the box to always use the selected player to open files of this type > ok.
That should fix the icon thing.

Red files in your library mean they're not being shared. Try refreshing the page or restart LW. Or, you can change each one manually by right clicking > share file.

To see all the info about your downloads, right click on the column header of the download pane. You'll see options like name, size, status etc. Tick whatever you want to show during download:wink:
