Ning import plugin Troubles

I’ve installed it and I’m receiving the following errors. I’ve gone over every inch of the site for weeks. Can anyone lend some insight? Maybe this is no longer working?

“Change the permissions on your wp-content/uploads folder to 777. This *shouldn’t* be necessary, but it might avert some problems. Be sure to change it back to something more sensible afterward (755 or 744).

Houston, we have a problem

In order to run the importer, you must first use your FTP program to upload the contents of your Ning export into a directory called ning-files in your wp-content directory. The plugin couldn’t find a valid members file at /home/content/p3pnexwpnas09_data01/97/2490697/html/wp-content/ning-files/ning-members-local.json, which probably means that you haven’t uploaded the files to the right place. Upload your unzipped export to the json directory, and try visiting this page again.”
