CS5.5 _mmServerScripts/MMHTTPDB.php Error Code 404

Hi All,

I've just uninstalled Dreamweaver CS4 and installed Dreamweaver CS5.5 instead, Whenever I try to make a new MySQL connection on CS5.5 OR test a query on a connection that already exists, it gives me the erro below "although" the pages that previously developed in CS4 work properly on localhost with all browsers. Following are information about my inviroment:

• OS: Windows 7 (32bit)
• Web Platform: XAMPP 1.7.4
• Dreamweaver CS5.5
• Web & DB Servers are UP & RUNNING with dynamic pages display properly on all browsers
• I am working on a msi laptop config: Core i3, 4GB DDR3
• File http://localhost/cloud/_mmServerScripts/MMHTTPDB.php exists

Answer for this question is highly appreciated. Thanks in advance.
