Q&A v 1.51 fatal error

[necser]

qa-util-emailer.php doesn't exist on 1.51 installation.

I get: Fatal error: require_once() [function.require]: Failed opening required '/home/qa/public_html/q&a/qa-include/qa-util-emailer.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/qa/public_html/q&a/qa-plugin/spammer-checker/spammer-check-event.php on line 18

Possible to update for 1.51?

Thanks!
