Error every time trying to use MSN Messenger with Windows 7 64 bit

Help. New machine with Windows 7 64 bit. New install of Windows Live and I
really want to use Messenger.

Every time I try to use Messenger, it crashes and brings up the dialog to
"close" or "debug"

When I go into the debugger, this is the message:

Unhandled exception at 0x73122ee5 in msnmsgr.exe: 0xC0000005: Access
violation reading location 0x00000018.

I tried these suggestions, but still get the error

Here is the stack trace:

I still get the error if I try to log in using MSN Messenger. However, I
figured out that if I launch Live Mail and use that application to log on to
messenger, it then works. Very strange.

So I have a very poor workaround for now, launch "Windows Live Mail" and use
that application to log on to the "Live Messenger".
