[Plugin: The Events Calendar] Version 2.0.5 install error

Fatal error: Call to a member function add_cap() on a non-object in D:\- Applications\Installed\xampp\htdocs\clients\roywales\wp-content\plugins\the-events-calendar\lib\the-events-calendar.class.php on line 741

The earlier version of the plugin, 2.0.4, install fine.

I have deactivating all other plugins and tried using the default 2011 theme.
