(Update 2/2/05: Based on some great investigative work done by Rick, Katie, Mark and Deepa we now believe that the root cause of this problem is a Trojan. See below for more details.)
(Update 1/20/05: Based on feedback from Djamu I’ve reduced the number of steps to resolve the problem.)
(Update 1/17/05: I’m looking for someone who is experiencing this problem who is willing to work with us on the phone to help us find the root cause. We’re looking for someone located in the US preferably. If you’re willing to work on this issue please send me an email at: messenger_support_space AT hotmail.com.)
(Update 1/13/05: Working with Deepa we’ve managed to cut the number of steps down and reduce the number of DLLs that have to unregistered & registered. Also note that if you have unchecked the "Check for Server Certificate revocation" option you should turn that back on. Let me know if you need instructions on how to do that.)

Or, if the were running 6.2 they would get this error:
