I have a WAMP set up and my server is local. When I try to create a connection to my database from Dreamweaver I get this pop-up error message:

Http Error code 404 file not found. Hera are some possible reasons for the problem:

1) There is no testing server running on this machine.
2) The testing server specified for this site does not map to the localhost/_mmServerScripts/MMHTTPDB.php URL. Verify that the URL Prefix maps to the root of the site.

What could be the problem?
