Mail merge works great from Word 2007. When trying to do mail merge from CRM it appears to work until I click "Begin Merge". I do get a dialog box to download or open the sugar token file. Once I try to open it, however, I receive the error message in Word: "Client found response type of 'text/html; charset=UTF-8'; but expected 'text/html'. The request failed with an empty response.

I'm running CE 5.2i on CentOS 5.3 with php-5.2.9 from the test repo. There is nothing in sugarcrm.log. I'm using Firefox as the browser. I get the following error in the Apache logs:

[error] [client 192.168.17.129] PHP Fatal error: require_once() [<a href='function.require'>function.require</a>]: Failed opening required '' (include_path='/var/www/html/include/..:.:/usr/share/pear:/usr/share/php') in /var/www/html/soap/SoapSugarUsers.php on line 1452.

I've looked into the SoapSugarUsers file on line 1452, but I'm not really sure what to try next.
