Recycle Bin quit working

I think the problem started when I ran Earthlink's PC FineTune and
accidentally closed the program while it was running.

Now, both while running PC FineTune and in general, I get an error message
whenever a file is attempted to be deleted (either by myself or that
program). The error message says:

"Error Deleting File or Folder
"Cannot delete [name of file]: The directory or file cannot be created."

When it talks about a file not being able to "be created," I suspect it's
referring to its attempting to create it in the Recycle Bin, but don't know
for sure. What I do know is that if I double-click on the Recycle Bin it
attempts to produce a listing of its contents but no amount of searching
(with the flashlight) reaches a conclusion. It just keeps searching
endlessly.

My repeated attempts to get help from Earthlink have proved less than
useful. All they do is tell me to unistall PC FineTune and then reinstall
it again. I've done that several times and it's just been a waste of time.

I hope someone here can help me get my Recycle Bin working again.

Thank you in advance,
Glen
