Of course you can always search your files via your computer search, eg: search .mp3 or .avi, etc. to see where they all are. Then re-add that folder as a shared folder.
You might have downloads set to not be shared after downloading. Or someone has tampered with your settings whilst you were afk.
For fast & easy access, go to your LW Library window, select Saved Files folder & press the Explore button. Sample image here:
Using Library Explore button to access downld folder (click on link) & the folder will open up for you.
Also keep in mind if you hover your cursor over the saved files or shared files folders in the LW Library window, it will show the directory location in a contextual popup window.
