The main download button for this project is linking to the docs instead of the actual nusoap source files. People using one of my Drupal modules that relies on this are getting the docs not realizing it's the wrong file and thus getting stuck because the lib subdirectory is missing.
Thanks. I looked at this a couple of times and have finally figured out how to change it. SourceForge provides a lot of options for projects. In this case they added something and defaulted it to the wrong file.
