Question about Outlook Express

Hello,

I am having a problem importing my Outlook Express Windows Address Book (WAB) from my old PC (running Windows XP) to my new computer that is using Windows Live Mail (and running Windows 7).

On my old PC, I had organized my WAB (which contains over 5,000 contacts) into various folders/categories.  I also had most of the email accounts set up to include First and Last names, as well as email addresses.  I exported my WAB from the old XP computer and imported the WAB into Windows Mail Live on the OS7 computer by using the "in mail" features on both systems.  Now, here is the problem:

While the new PC/Windows Mail Live indicated that the WAB transferred successfully, it did not import in exactly the same way that it exists on the old PC with XP using Outlook Express.  Some of the contacts appear to be missing all together, others are not showing in the folders/categories to which they belong, and many seem to have lost their First and Last names, instead showing the email address both under the email category and under the user name category.

Does anyone know why this is happening, or how I can correct it?  Am I doing something wrong?  Is there a better way to transfer the WAB?  Unfortunately, my knowledge is limited when it comes to this kind of thing, but generally I can resolve most issues I run into through trial and error.  This, however, has been one area that I've found no success in fixing.  Any help or direction that anyone can offer would be greatly appreciated.

Thanks in advance,
