[Typo3] newest articles error

[Murtada Shah]

 Fatal error: Call to a member function on a non-object in 
/home/macyouth/public_html/typo3conf/ext/moc_articles/pi2/class.tx_mocarticles_pi2.php 
on line 108

I put a 'Newest article' on my page, but I get that...

I installed templavoila and used it to add it, since it requires tv. I also 
tried regular content, but the same error persisted.

Any ideas?
