ioncube loader error on php website hosted on GoDaddy

I have a shopping cart website site up at http://www.santamariahorsesupply.com.  I just installed a classified ad system at http://classifieds.santamariahorsesupply.com.  The classified ad system works perfectly, but now I can't get the shopping cart system to load.  I get the following error message:

Warning: dl() [function.dl]: Unable to load dynamic library '/usr/local/php5/lib/php/extensions/no-debug-non-zts-20060613/ioncube_loader_lin_5.2.so' - /usr/local/php5/lib/php/extensions/no-debug-non-zts-20060613/ioncube_loader_lin_5.2.so: cannot open shared object file: No such file or directory in /home/content/s/m/h/smhorsesupply/html/includes/prepend.php on line 2

I contacted GoDaddy and they had me enable ioncube and update the php5.ini file, which I have done.  But I am still getting the error message.

My php5.ini file contains the following:

[Zend]
zend_extension=/home/content/s/m/h/smhorsesupply/html/ioncube/ioncube_loader_lin_5.2.so


I also have a php.ini file which contains the following:

register_globals = off
allow_url_fopen = off

expose_php = Off
max_input_time = 60
variables_order = "EGPCS"
extension_dir = ./
upload_tmp_dir = /tmp
precision = 12
SMTP = relay-hosting.secureserver.net
url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=,fieldset="

[Zend]
zend_extension=/usr/local/zo/ZendExtensionManager.so
zend_extension=/usr/local/zo/4_3/ZendOptimizer.so


I'm not sure if they're trying to share the same file, or what is happening.  Thank you!
