Talon:
Normally you don't have to restart anything. If you found were the Shared folder is located on your computer then that is were ALL previously downloaded files are; unless the files you are talking about was not completed (in wich case you'll find it in the incompletes folder) then just browse the shared and it should be there.

Void:
If LW is otherwise working normally (aside from the player freeze of course) then quit the app and restart it to get it going again. If LW has entirely frozen then you have to Force quit it.

Remember, it is best to ease up the computers' load (don't have too many programs on at the same time unless you have a very good RAM). Also, remember that even an idle program is indeed using up RAM memory, thus slowing your computer.
