Fatal Error when trying to activate plugin

I just tried to install Protected Content v 1.1.0.2, and when trying to activate the plugin, got the following error:

Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM in /home/storage/2/1e/41/ogerente/public_html/wp-content/plugins/protected-content/app/class-ms-factory.php on line 207

The plugin doesn't activate.

Any suggestions?
