Hi All.
Here’s an update for those people running into this goofy problem. We’ve
found the source and are currently working on a fix to the problem.
If the high-order bit of the first byte of the MAC address is on (usually
indicating a multicast or broadcast address) or the Vendor ID is returned as
0xffffff (indicating a vendor without a IEEE-registered code) then a system
call gives us something we don’t expect which causes the missing contact.
In order to workaround this issue until we have a fix handy, users can
uninstall all Windows Live Essentials Apps (v14.0) off of their machines and
then install 2008 Messenger and ignore the Optional upgrade.

Actually, this set of steps might be easier for everyone:
If you log in and you are missing contacts, please do the following:
1. Start -> Run -> type "msinfo32"
2. In the system information dialog that should show up, choose "components"
then "Network"
3. With "Network" selected go to the File menu and choose "Export" and save
the file as "Network.txt" to your desktop.
Please email me (livebeta_nick@newsgroup) that file as it shows which
networking components your machine uses to talk to the internet.
Thanks again for all of the help!
