problems after upgrading

Hi Guys,

Our CMS was upgraded last week. We were having an issue with our rss feeds where the cmsadmin had a lower case "a" which needed to be uppercase but these were easily fixed. However, we are still getting some errors on our RentHousesNow site. This error code appears when you try to go to the site.

Warning: main(C:/Domains/renthousesnow.com/wwwroot/cmsAdmin/lib/viewer_functions.php): failed to open stream: No such file or directory in C:\Domains\rentittoday.com\wwwroot\cmsAdmin\plugins\saveAndCopy5\saveAndCopy.php on line 12 Fatal error: main(): Failed opening required 'C:/Domains/renthousesnow.com/wwwroot/cmsAdmin/lib/viewer_functions.php' (include_path='C:/Domains/rentittoday.com/wwwroot/cmsAdmin;C:/Domains/rentittoday.com/wwwroot/cmsAdmin/3rdParty;.;c:\php\extensions') in C:\Domains\rentittoday.com\wwwroot\cmsAdmin\plugins\saveAndCopy5\saveAndCopy.php on line 12

This site has worked for a while but now does not. The code that we use to call the database is:

<?php require_once "C:/Domains/rentittoday.com/wwwroot/cmsAdmin/lib/viewer_functions.php";

list($real_estate_rentalsRecords, $real_estate_rentalsMetaData) = getRecords(array(
'tableName' => 'real_estate_rentals',
'perPage' => '4',
'orderBy' => 'RAND()',
));

?>

Any ideas for fixing this are greatly appreciated :)
Thanks,
Lauren
