I too am having issues with LW5, I don't have a genre option anymore and my sharing folders won't show up anymore, only the new songs I have downloaded.
I used to share upwards of 1,000 songs now Im at 90.
It also wont download directly to a folder I am working on so I have to search through all 90 to find the new song and then transfer to folder, yuck, tis taking too long
