Dropbox 0.7.2 not installing

Trying to install this plugin on fresh install of latest Omeka, receive this message on Plugin screen:

Dropbox
Version 0.7.2 by Roy Rosenzweig Center for History and New Media
Allows users to upload files outside of Omeka and batch-add many files at once.
Get support
This is not a valid plugin.

Problem solved. When I unzipped the plugin in the plugin folder, the resulting folder name was “dropbox-0.7.2”. Deleted the revision number and everything works.
