Question about Outlook Express

The search feature in WLM 2011 doesn't return the correct email messages when I enter the 'before' and 'after' dates.  Please note, I entered the correct dates and mail box folder but the returned messages from the search do not match the dates.  e.g. The result of a search between the dates: 18/10/2012 and 09/10/2012 would return messages between 25/10/2012 (current date) and 20/10/2012 which is entirely wrong. 

I've tried running the Microsoft Fix It utility found here @ http://windows.microsoft.com/en-US/windows-vista/Troubleshoot-problems-with-Windows-Mail but it didn't find any error with Windows Live Mail search feature and Windows search in general.

I'd like to inform you that I'm running WLM 2011 on Windows 7 64 bit operating system.  This Microsoft article here @ http://support.microsoft.com/kb/969165 looks like it relates to my problem as it could be caused by a 64 bit search filter issue.  However, this article applies to version 3 of WLM which may be different to my one.  My WLM shows up as version 2011 with a certain build code.  The proposed resolution on this article requires some sort of reconfiguration of the registry which I'm reluctant to do at the moment as this article may not to apply to my case.

I'd welcome any suggestions about resolving this issue.
