new install ver Zen Cart 1.3.5

http://www.hiddenvalleybooks.com/zen...php?main_page=

gets this message:

Fatal error: Call to a member function on a non-object in /home/hiddenva/public_html/zencart/includes/classes/currencies.php on line 31
I installed ZC and know nothing about it, starting the learning curve at the bottom.

How do I fix this?
