Just installed this plugin, get this error

Fatal error: Call to a member function setToken() on a non-object in /htdocs/www/wp-content/plugins/simple-dropbox-upload-form/wp-dropbox.php on line 272

the plugin is used here:

We would appreciate a solution fast as we have a good few people waiting to upload stuff.
