I download a song it used to show in library but now nothing it wont even show my shared files go up in numbers

Hi

There seems to be a new problem with the Shared File. In Preferences under Saving, check which directory is currently nominated for saving downloads. If you follow that path, you should find the "missing" files there.

If that does not "find" the files, use your utility search engine and search for any file whose name you remember and that should find it.

If that does not work, worrying is an acceptable response and you should run your disk utility and repair your drive.

For the future, go to Preferences and create a new root directory for accepting downloads (say Shared2). That usually resolves the problem.
