Updating database error

Can anyone help me, I tried to update to the newest version of the Disqus module and I end up getting this.

An error occurred. http://netbookupdates.com/update.php?id=27&op=do
Fatal error: Call to undefined function disqus() in /home/netbooks/public_html/sites/all/modules/disqus/disqus.install on line 42

Thank you in advance!
