If the permissions are correct on the file and the file is in the correct place and you created the plugin using the correct hook and it is active, then I don't know what the problem is. I suppose you can check your error_logs (if you don't know where they are, ask your host) and see if anything is in there.

As for creating a file.... I just create a file and when I go to save it, I save it as name.php. I don't save it as a text file and then rename it. That could be your problem - I really don't know.
