Cannot install Plugin in Moodle 2.2.2

I have followed the install guide for version 0.7 of Joomdle on Moodle 2.2 but come up against a problem when trying to install the Joomdle authorisation plugin. I get a 404 error File or Directory not found when trying to upgrade and the plugin does not appear on the list. The auth files have been zipped to the correct directories and I have removed and reinstalled a few times. See screen grab for info on how the plugin appears on the plugin check.

Any help appreciated.

Found the problem. I was using the incorrect joomdle auth zip file. Case closed.
