I ran into the same problem when I first started. I had to manually "Add folder to Share"
Under your Library Tab, click on File, then "Add folder to Share"
A box titled "Select Directory" pops up.
Click on the icon that has a folder with an up arrow in it.
You should see three folders listed: 2.4.4, Shared, and Incomplete.
Click on the Shared folder then click Select.
The shared folder should now appear in your Library.
You can personalize this through "My Computer" and add different folders for different users.
After you add the folder, click Refresh and it should save it there. If you don't, you'll have to "Add a folder to Share" each time you log in until you do Refresh.
Let me know if you want me to tell you how to personalize your Library - it's really easy.
