Just wait. Whenever LW says "Sharing X/Y files) then it means that it hasn't finished hashing (or whatever) the rest of the files. In time (hopefully not too long), the files will be shared and you will see something like "Sharing 1 file" (duuh).
If it finishes this process but it says that it ain't sharing anything, go to your library and click refresh.
