Hi,
I really don't know why you'd want to use the LW player (I find it pretty awful) but if you really want to use it, try this: Delete LW's preferences folder when LW's properly closed. See point 3 here & also point 2 if you've used older versions of LW in the past (there could be a folder in either location).

This will kill all of your settings within options, you'll have to go back through afterwards & reset things.
