Because this forum is dedicated to validation issues, you’ll need to contact outside support for the expertise necessary to troubleshoot your non-validation related issue. You can do so by posting or searching in the Vista pubic newsgroups, found here: http://windowshelp.microsoft.com/communities/newsgroups/en-us/default.mspx or by following this link to Product Support Services. Microsoft has a 90 day free support period that starts on the day you first acquire Vista.
If you bought your computer pre-installed with Vista either from a computer store or an original equipment manufacturer (OEM) like Dell or Gateway, you’ll need to contact them for support.
