I did some search on internet to see there are any references to similar errors. The one given below looks interesting. http://social.msdn.microsoft.com/forums/en-US/sqlsmoanddmo/thread/94f476c9-6d22-44e2-ba15-0786c0dfffaa/

It speaks about two downloads/feature-packs and probably they could help fixing the problem you are facing. Meanwhile, let me try to configure it on another computer and see if I can find some thing that can help you.
